Your idea that Maguire's Peter is awful or what not is diminished quickly when you say "social ******", fyi.
But...his talk with Otto was fascinating, imo. Peter talking to his idol and someone that could very well be a mentor, but also someone that Peter could turn into metaphorically.
The new Peter is just as awkward. The scene at the school with Gwen Stacy was as upsetting to me as Maguire's Peter talking to any female besides Aunt May.
He only let go of Sandman in Spider-Man 3, though, while Peter thought he met the real killer in the first one. Nothing about him letting Sandman go should hurt Spider-Man 1, and especially 2. As I said, Spider-Man 3 was ruined from the beginning and destroyed any credibility Maguire's Peter Parker/Spider-Man was given the past two films and even letting Marko go. As I said, that's only on Spider-Man 3. No way anyone should say it killed the last two films because of how S-M 3 was written.
Biased critics giving TAS-M a lesser score because of it being a reboot? That didn't really kill Batman Begins, Star Trek, et cetera. Imo, TAS-M was diminished by some critics because it felt too much like the '02 film in many ways. And that is a bad thing if you ask me. TAS-M should've felt new, refreshing and different.
