Peter's always been good at school and had good grades in the comics, so this was authentic. Same in the Raimi movies, in SM3 he was doing just fine once he stopped blaming Spider-Man for him not being competent enough to keep up.
So SMH was being true to the comics.
Nah, it was an alien battery.
And then we found out things weren't so bad in the first place and Peter was just being incompetent. He could've easily mended things with MJ or done better at school if he put the effort in, he was just blaming Spidey when he could've done better to begin with.
Nah, he's just not an incompetent.
Raimi's Peter had no problems in High School.
True to the comics.
Once May moved out of her house and to an apartment her money problems were gone, THIS May was smart enough to do that from the start.
No, he was dealing with being part of a bigger world while Raimi's Spidey had it easy in that he was the only hero.
