Spider-man is pretty famous for being one of the first super heroes with real world problems. He's constantly blaming himself for things that go wrong like Uncle Ben dying, Gwen Stacey's swan dive, Venom's existence, etc... So I don't think the teen angst angle is out of character for him.
Maybe his smartass banter while fighting is throwing you off a little.
Peter Parker practically invented teen angst.
