I'm sure I have more, but for now I just want to name one.
Sam Raimi's Spider-Man. Sure, he was never in The Avengers. Sure, Tobey Maguire's delivery has a bit of room for improvement. Sure, the computer generated effects were still new at the time. And sure, most Marvel movies around this time could've been better, with most of them not getting their footing until like...2008. However, this movie was very special. Not just to me, but in general. The cast they had was nice. The retcon of our hero producing the webbing from his wrists instead of relying on the boy genius to the max with him SOMEHOW making an adhesive that he could manipulate better than a Spider does with its natural adhesive. And Danny Elfman's composition is nothing short of glorious. This movie makes you go through a variety of motions. It cracks a few jokes, has some compelling action, and tugs at your heartstrings.
I don't care if it happens to air on TV, if someone puts it on a service like Hulu, Netflix, or Disney Plus. I'll watch it.
