As for TASM2, I really can't fathom the viewpoint that it somehow out of character for Spider-man. That kind of scenario is a staple of comic book lore.
Nope it ain't. If that's how it was you'd have a bazillion proper examples. But nope you only had crazy OOC tales like Spider-Man Reign and DKR.
Why are you having difficulty fathoming something that is factually true? It should be the other way around. Nobody is saying that a hero taking some time out to grieve because of a tragedy or a loss of a loved one never happens. But not for months on end abandoning their superhero duties while the people/city they protect suffers like in TASM 2, which is very much out of character for Peter. But you're here posting Green Lantern facial expressions in some attempt to validate that, which is something that makes no sense at all.
That doesn't happen, unless you're talking about those elseworlds out of canon tales, which are the only examples you've been able to cite, which are not valid examples for in character traits because the sky's the limit on the insane things they do in tales like that, some of which have already been cited to you.
Even in the infamous 'Spider-Man no more story' in the comics, he didn't abandon his Spider-Man duties for weeks or months. It was a matter of days, and during the story we see him go through personal conflict about what he's doing, and do some soul searching, just like in Spider-Man 2. As others have already said, with TASM 2's sloppy one minute montage of Peter's months and months of quitting and wallowing in misery, we see nothing insightful like that. Just him spending countless time hanging around Gwen's grave.
You mentioned X-Men Days of Future Past as using the same plot device as TASM 2. It absolutely 100% did not. Charles Xavier had not formed his X-Men team yet. He did not break up the X-Men and sink into depression. He just abandoned his school for mutants. The X-Men had not happened yet, which is why Wolverine was telling him later that when he does meet the X-Men team like Scott, Storm, Jean etc in the future that he has to guide them, lead them because they'll need him. Had he abandoned the X-Men team and done that, then you'd have a valid movie example.
It's the same with The Dark Knight Rises example you tried to use on the previous page. You said Batman quit for years because of Rachel and Harvey's death. Also 100% untrue. He quit because Gotham didn't need him any more. Organized crime was cleaned up because of the Dent Act. This is verbally stated several times in the movie. He didn't abandon his city for a long time because he was wallowing in grief like Peter did in TASM 2. That didn't even happen in the comics when he lost Gwen. He had reason to feel guilt for her death in there, too, unlike in TASM 2.
Spot on.
While I obviously think the movie was trying to make that scene charming and cute, it came across as self-centered and attention-seeking to me; obnoxious, even. There are just a lot of bad decisions about these movies, and seriously ... That makes me feel bad for the actors. I've said it many times, and I'll say it again: The cast deserved better.

Plenty of time for "Da Rhynooo!" though.
