Guys, you shouldn't compare him to his character in the Ultimate Spider-Man series. If you read the little issues he's been in, you'll see he is very different in the comics. He isn't such an idiot and he seems a lot more mature, although he's still a kid and he makes some bad jokes. But I watched USM and I also read all his issues (which like... four), and I find him a lot more likable in the comics. I think Loeb is writing here stuff he just can't put in a kid's show. I mean, in just four issues (where Sam isn't even the main character), he saw a planet being destroyed even when he tried to save it, he ended up in a coma and he was almost killed by Scott. So yeah, I don't think you can compare him to USM!Sam.
