The Spiderman movies have definitely 
changed the story from the comic book. Watching the first of the film , I
 wasn't happy with the depiction of Peter Parker as more self-centred 
and vain, which is unusually in the context of the comic books. At this 
moment, Peter Park goes through so much crap that it's a wonder he 
doesn't commit suicide (it's kind of like Jack Bauer in 24).
Some
 factual points that were changed, which I'll agree was necessary to 
make a decent movie, are as follows: The Venom costume is an alien being
 acquired during the Secret Wars battle with the Beyonder (which was one
 of the best "cosmic" series Marvel has put out). Spiderman doesn't want
 to kill villains; even when he is beaten and pulverised, he holds back 
from taking the ultimate step (in fact, it is rare to show people dying 
in the comic books). Harry Osborn is more like the depiction of Normie 
Osborn (the son of Harry and Liz Allan) who is friends with the daughter
 of Spiderman (Spidergirl). Gwen Stacy is killed by the first Green 
Goblin (Norman Osborn). The people of New York have rarely been on the 
side of Spiderman. J. Jonah Jameson has always had a point in saying 
that it is people like Spiderman who create the villains. And so on.
It's
 difficult for me to reconcile what I know of Spiderman's history with a
 movie story that does its best and I admire that. A problem with the 
movies is that they can't intersect with the other characters from the 
Marvel Universe. It would be great to have movies like the Secret Wars 
or the Infinity Gauntlet, War, and Crusade series where a bunch of the 
Marvel superheroes get together and the stories make more sense (for 
example, explaining the origin of the Venom symbiote), but I guess that 
would be a logistic and budgetary nightmare.
Halfway
 through the movie, the story gets in line with what you'd expect from 
the book. The rejected symbiote bonds with a humiliated Eddie Brock to 
become Venom, one of the coolest villains to be introduced in the later 
years. The Sandman is a villain who is ambiguous. And Spiderman has a 
run of bad luck and is pummeled constantly but triumphs in the end 
against all odds.
I
 once wrote a review of the Batman series where I connected them to a 
lot of the comic books (I own a huge number of Spiderman comic books) 
and some other reviewer criticised my review. The perspective I offer is
 fairly unique: it is based on an experience I can't ignore or negative,
 and I think it helps place the movie in context of a long history of 
the books. So if you're interested in the saga of Spiderman beyond what 
you see in the three movies, I recommend buying some of the great story 
arcs of Spiderman just to see how complicated and mythological the 
creations are.
