I absolutely don't mind more lighthearted stuff like what we see in Guardians. But extremely goofy stuff like She Hulk and Thor LT i do. I get what you are saying about tastes and all but this is a shared universe. It's all connects. I want to watch all of it and I'm sorry She Hulk just completely pulled me out of the MCU narrative.
With some shared universes, I'd be inclined to agree (e.g. I feel
Star Trek: Lower Decks went too far into implausible absurdity at times). But the MCU is just replicating what the comics have always done, lumping together wildly disparate genres and tones into a shared reality. I can't fault it for being true to its inspiration.
Largely due to DEADPOOL, perhaps. John Byrne's SHEHULK seemed to me a pioneer. It beat her Stan Lee debut, most of her initial issues and her AVENGERS stint following the cancellation of her first '80s book.
Oh, no, comics breaking the fourth wall goes back to the 1940s at least -- like that issue where Batman let Robin beat up a bunch of bad guys single-handedly as an object lesson to the kids reading the comic that one wholesome, right-living pre-teen boy was stronger than any number of filthy criminal thugs. A lot of early 1940s comics would have the characters occasionally address the audience or wink at being in a comic book. The early
Fantastic Four comics played fast and loose with the fourth wall a lot, having Lee & Kirby be characters in the book and having the FF read their own comic and answer reader letters. It was loosely rationalized as an in-universe comic dramatizing their real adventures, but the writers were definitely playing around with the reality of the series. If they didn't break the fourth wall entirely, they were certainly leaning out its window.
It's why the first two seasons of Picard are so much more compelling to me because the world feels like it is carrying on, people die, people drift apart this is organic. It is unrealistic and very boring if the same set of characters do absolutely nothing else with their lives for decades at a time. When Discovery introduced the Burn it was this big shake up of the status quo and then we learned Vulcan was now Ni'Var it was development. It's why so much of the Star Trek relaunch novel era falls flat to me this necessity to reunite and keep everyone together is such a bland trope.
Really? The post-finale novels didn't really do that, though -- they had the TV characters move on to new roles and had original characters take their old jobs. The DS9 novels took a while to bring Sisko back, then had him retire to Bajor while Kira remained in command of the station, and similarly O'Brien and Odo remained absent aside from eventual guest-star roles, and the novels developed a bunch of new characters like Vaughn, Prynn, Shar, Taran'atar, etc. Later novels made bigger (and controversial) changes like having Sisko return to starship command and Kira become a vedek. The
Voyager novels continued to focus on the series's core cast, but spread them around in different roles and different storylines rather than having them stay aboard
Voyager. Most of them eventually ended up back in the Delta Quadrant, but spread among multiple ships of a slipstream fleet. My
Enterprise post-finale novels have the former NX-01 crew in mostly different roles on multiple ships, alongside a fair number of novel-original characters, or canon characters from the period like Tobin Dax and Bryce Shumar. Then there are the
Titan novels that picked up on Riker & Troi's transfer at the end of
Nemesis and gave the
Titan a crew that included Tuvok, Melora Pazlar, and quite a few book-original characters. The post-
Nemesis TNG novels still had Picard, Crusher, La Forge, and Worf in their old jobs on the
Enterprise-E, but with original characters filling out the crew.
So I'm not really sure what your impression of the "relaunch" era is based on.
