That's not quite how the cause and effect happened. WB brought in Whedon as a script doctor well before Snyder lost his daughter, while the film was still being shot, because they weren't satisfied with how the film was turning out under Snyder. People forget that WB was dissatisfied with Snyder's work after Batman v Superman was panned, and they were already pushing him out of his creative role in the DCEU in favor of Geoff Johns. So Whedon was already involved in reworking the film when Snyder's tragedy happened, and taking over as director for post-production and reshoots was merely an expansion of his role.
So even if the tragedy hadn't occurred, Snyder would still have had his creative control taken away and JL would still have been massively altered from what he wanted. After all, both BvS and Suicide Squad were heavily reworked at studio insistence, remember. So there was never a chance that JL would've been Snyder's unadulterated vision. The only reason the Snyder Cut was eventually made was that WB wanted new material to put on HBO Max during the pandemic when new production was mostly shut down, and it was convenient to capitalize on the hype that had built up around it.
And in all honesty: I watched both versions - the allegedly bad version and the supposed good version. I don't see it as this cut and dry. Back in the day, I sat down, took my notebook and wrote down a list of pros and cons concerning the Snyder-Cut. And while the pro-coloumn was not entirely empty (I distinctly remember, that I liked Alfred Pennyworth, snark-master galore and "This is Alfred, I work for him"), I couldn't help but notice more parts in the "con"-column.Of course, one part is the absurd length of that movie. And yes,
now Snyder might see that as a series, but that's not, what he was hired for. By the way, let's put a pin in the Snyder-Argument, I'll revisit that one later.
Another part, that really annoyed me, was, that Snyder thought "hey, let's overdo the whole slo-mo-thing", the "Wonder-Woman-Yodel" (but that's now completele been debated to death) - I'd rather bring out three scenes, where I said "Yeah, Snyder, that's not better than the supposed 'bad'-Cut."
Take this "Barry saves the woman from dying in a car-crash" - okay, I have seen the TV-Series "The Flash" with Grant Gustin and Candice Patton, I know that Barry Allen and Iris West have their thing and after a short google-search, I knew, that this woman in the car-crash was supposed to be Iris. But every movie could be someones first exposure to these characters and seeing these characters interact with each other, without context, makes this whole scene creepy. This "touching her face, while he's in the speedforce"... ugh. By the way, it is also creepy, if we know the background, that this is supposed to be Iris.
Plus: This whole "truck driver eating a sandwich, slo-mo-cut on that seed falling down" is completely uneccessary.
Or take the "Wonder Woman fighting the bad guys in the Great Baily"-Scene. There, Whedon knew, that with just with two quick changes, this scene could've been made better - and he did. One: Wonder woman does not kill the first villain, when opening the door. Two: Wonder Woman does not explode the terrorist-head-honcho out of the building.But since those scenes were shot, Whedon had to lose the "Can I be like you"-"You can be anything you want"-Part, which is sad, since that's something, I put in the good-part of my list.
Another scene, that is vastly superiour in the Whedon-Cut: The unearthing of Clark Kent. Why? Here we only have Flash and Cyborg. They talk, Barry tries to bond with him (fistbump), gets denied this fistbump and earns it later in Not-Czernobyl.In the Snyder-Cut, we don't have the firstbump-scene, which makes it later come a tadbit unexpected and actually very strange, instead of that, we have Barry talking to Victor, if Wonder Woman would be into younger guys (?!) and we have Diana and Aquaman being present, standing there at the van, just talking and looking as if they wanted to get their hands dirty.
Then we have Wonder Woman looking like a fool, when she's talking to Alfred. Why? First of all, he needs to remind her, that she is standing in front of a laser, second of all, she needs to be told how to prepare a proper tea? And then Alfred says "oh, I'll do that myself"?
Did Whedon shoot this - after all, allegedly he told Gal Gadot, that he could make her look silly in the movie. Well, if
that doesn't make Wonder Woman look silly, I don't know, what would even qualify as "making her look silly".
And in the end, there is this whole "How to get rid of Steppenwolf"-scenario.
There I totally side with the Whedon-Cut. Hurting him enough, to make his underlings see, that he's afraid, which turns them against him? That's a smart tactic.
What's no smart tactic? Just punching the guy, stabbing him and then beheading him. This whole "ganging up on the dude" is not a very heroic behaviour from our heros, actually.
So, in conclusion, at least I - ignoring troubles and a**holish behaviours backstage - say, that the Whedon Version is the superiour one. It's shorter, has more humour and gets rid of Steppenwolf in a smart, creative scenario. That being said: the Snyder Cut is not bad, it's just not this awesome flick, that people tend to overhype it into.
Oh, and now let's address this whole "Snyder vs. the publisher"-thing.
Okay, his first movie in the DCEU, where he had more to do, than to play "producer", was "BVS". This movie comes in two versions. One cinematic, one extended. And I bought the blu-rays for MOS and BVS, and when I started watching BVS, I immediately took the "extended" one. And it's bad. I mean - really bad. Bland, boring, downright nihilistic... blech. If that version, I saw, the extended one, is that boring, I guess, I don't want to watch the cinematic thing.
Now, Snyder went public, said something like "Yeah, I know the theatrical cut is bad. I had to do it that way, since the studio wanted it to be short. But you can buy the better extended cut now!"
And I went like "Ain't that smart? You write a movie in a certain way, that it
needs to be at least 3 hours long, and when the studio says "are you nuts? Cut it down", you re-cut it, you cut out important scenes, so that you then can say "Yeah, I wanted to do it differently, but... see...the studio."
The Whedon-Cut is a whole different scenario, however, I'm sure, that, if he hadn't to step down, Snyder would've found a way, to sabotage his own work there, too - so, that he could nurish the tale of him being the auteur, who wanted to tell a whole different story, but, alas, the studio didn't let him.
Why do I know this?
Let's have a look at his latest movies - Rebel Moon 1 and 2...
I mean, there he worked with Netflix and they couldn't care less about the length of the movie. I mean, with a studio, that wants to bring the movie in the cinemas, needs to get butts in the seat, I can see, that they'd rather have a short 90-Minute flick, than a long 3-hour movie. But here? This is Netflix. this is "streaming movies from home", where the experience can be 3 minutes or 30 hours. But here, Snyder did the same thing. "Here's my inferiour version, since Netflix wanted it to be in a certain rating, I had to cut some stuff - but don't worry, the complete movie can be seen later in my Snyder-Cut".
Honestly, if I'd be a studio, that dude would never work for me.
