I think a lot of this is rose-tinted goggles.
“Remember the good ol’ days of Phase 1-3? The glowing praise for The Incredible Hulk? The way they totally didn’t waste Mickey Rourke on Whiplash? The way they definitely beat Fox with their version of Quicksilver? The way everyone in The Avengers wasn’t cracking jokes and making puns? The absolute banger that was Thor: The Dark World?”
Ant-Man is friggin’ Ant-Man, and far more in GOTG territory than Winter Soldier turf. But for all the wackiness in many of these films, I didn’t think projects like Loki, Moon Knight, Wakanda Forever, Werewolf by Night, Eternals, WandaVision, or FATWS were overly comedic, and stuff like Hawkeye and Ms. Marvel were just the right amount. And She-Hulk’s best comic runs are straight up comedies.
The only Phase 4 project that made me go “scale it back, please” was Love & Thunder, and that’s largely because it had a story, themes, and characters that really weren’t working with a lighter, sillier approach.
