It was good and I like it.
BUT, its biggest problem is that Peter Parker! He is not same as comics! I mean, here he has no problem to Miles's father die! But real Peter never let some body get kill and he try a lot to save him/her. And the worst one is that he has no problem for uncle Bens death!!!!!!!!!! However in first movie he was great!
The real Spider-Man fan, knows that the original Spider-Man is Peter Parker but this movie didn't show him good. Its true that this film is about Miles but it must show the real spider man just like the comics.
And the other problem is Miguel O'hara. In this film he is the boss and he is so wild! I mean he has never been boss and he is good Spider-Man.
Over all these, its animation was great -same as the comics- and it was amazing, its music was so great, easter eggs was extremely cool (Marvel Spider-Man, Andrew Garfiel and Toby maguire), and ....
At last, it was amazing movie for MILES MORALES FANS not for Spider-Man fans because the real Spider-Man fans know that Peter Parker (I mean Peter B parker) wasn't same as the real Spider-Man. Its true that he is not the real Spider-Man but he can't be like this when the only important Peter Parker is he!
I give it 4 out of five for that I said.
