I guess I should answer the question.
1. Color palette. All Marvel movies have this problem. In Watts' defense, he's one of the first directors at Marvel to try to fix this issue. He made the colors red/green/purple stand out, but the rest of the film still looks like mud.
2. Cinematography. Again, problem with all the Marvel movies. It's especially disheartening given all the Sony films had great cinematography. That's the one great thing Spidey had even when his movies were bad.
3. Aunt May. She wasn't in it much, but so far she comes off like the klutz of the Lee/Ditko era. Give me the strong independent woman Bendis and JMS reinvented her into in the early 2000s. In Feige's defense, he said the Aunt May issue from JMS' run is the one thing he wants to adapt the most from Spider-Man. I seriously doubt anyone reads that book and goes "Hmm you know what'd be better? Klutz Aunt May!
"
4. More bullying. I love Watts' idea of Peter being the poor kid at an elite school. It doesn't just make the bullying about Peter, it adds some serious social commentary to it. I wanna see more of that.
5. Flesh Flash out. Huh? Tongue twister
. Like I said I like their idea for the bullying, but their Flash still comes off one-dimensional. Flash in the comics was both a bully you love to hate
and a character that was fully dimensional. He doesn't have to be 616 Flash but make him just as nuanced.
6. Flesh out MJ. The one big change they haven't sold me on yet. the The fact they couldn't actually name her Mary Jane just screams of lack of confidence to me. If they don't have confidence in their new take, why should I? Still, they sold me on so many unconventional ideas for Homecoming I'll give them the benefit of the doubt. But overall it wasn't a good way to introduce the character (not the take, the name).
7. Set up Osborn. After all the working class parallels and big business talks, Osborn just fits too naturally in this franchise. Moreso than in any of the Sony films. It would be a huge missed opportunity to not have him, and I think they'll introduce him sooner than we expect.
8. Uncle Ben. Mention him. Talk about him. And most importantly, do it in such way it doesn't feel contrived.
