Sam Raimi was not known for helming big budget fantasy movies before Spider-Man (and yes, I'm including those low-rent TV series as not being evidence of ability to handle something high concept/big budget), but he ended up making two among the very short list of great superhero movies.
In other words, anything is possible.
Sam Raimi still made great movies before Spider-Man, even if they weren't high budget you could tell he could easily handle characters that like to quip and that he could do a lot with only a little. The guy on "Shazam" hasn't made anything that qualifies him to kiss Raimi's feet, much less make a superhero movie. He made small movies pretty much no one saw, and a sequel to a terrible spin off of a good horror movie. That doesn't qualify someone to direct an episode of
Arrow, much less make a movie. But, this is the same company that hires hacks like Zach Snyder and David Ayer, so they obviously try to hire the worst people for the job and then accidentally hire actually talented people like Patty Jenkins every so often.
Peter Jackson also did mostly low budget horror movies before he did Lord of the Rings.
Yes, and they were shit. Dead Alive is one of the worst horror movies I've seen (and I've seen some bad ones). One could easily argue that the LoTR trilogy could have been made by almost anyone if they had the same resources and screenwriters (Jackson wasn't the only, or main, writer on any of the original trilogy). Based off the Hobbit, while I think that the LoTR trilogy is great it is literally the only goood work Jackson has done and I'm convinced any moderately capable director could have matched it since Jackson is a bad director generally and he pulled it off.
Sorry to disappoint but Sandberg's currently out scouting for locations, and they've already booked shooting dates early next year in Canada, so pre-production is well underway.
On the plus side, you get to tell us how they're doing Everything! Wrong! for the next year or so, so there's that to look forward to...
Oh yes, because no movie has ever been cancelled in pre production, or had radical changes. There is also no chance of a director getting fired in pre-production, either. Especially not in superhero films, there is just no example of that happening

Until the movie actually starts shooting, it could easily be cancelled or have major changes to the crew behind the movie.
Also, yeah, my favorite superhero is getting metaphorically screwed with a rusty railroad spike. There has never been a superhero movie that pissed me off so much, so regardless of your rather dickish comment I will certainly be voicing a lot of displeasure about the continued destruction of Captain Marvel, something that started around the time of Countdown to Final crisis in the comics and has gpotten worse and worse by the year. At this point, I think DC is still bitter that Captain Marvel outsold Superman in WW2 so they're destroying him over and over as revenge.
To be clear, the shitty, cheap director is just a symptom of the problem. The real issue is that geoff Johns doesn't like Captain Marvel, in fact he wrote the absolute worst mainstream stories featuring a version of a character in Captain Marvel's 70+ year history. Now he's helping to run the movies, so the Earth's Mightiest Mortal is beyond fucked just because of that. Choosing a bad director is something to directly critisize right now, but its going to get worse unless the movie gets a mercy killing.
