How much different are they. I never really read the comic books but of the of the information I have found from the internet this is what I have found so far.
Spoiler
MJ was not actually Peter's lone love. She was actually Peter's third girlfriend during the comic strip series. And I don't think there affection for eachother was quite as strong as what was indicated in the movies (as in the comic book even after he met MJ he continued to see other people). They did not grow up living together right next door to eachother. MJ only moved in next door to Peter in the comic book during highschool.
That was pretty much what I just found out. Anybody know of anything else that the movies stray away from from the real Spider man story.
