Mild mannered Peter Parker is bitten by a radioactive spider, resulting in super-powers that grant him the proportionate abilities of the eight-legged arachnid. Leading into a story where the young webslinging teen-ager truly learns that "with great power comes great responsibility".
As a comicbook nerd, I was pleased with Marvel's 1st. initial effort at trying to do what Burton did with the Batman: Introduce the webhead as a serious legitimate property for film.
One of the things that usually bugs (pun unintentional) me about comicbook based movies is that the changes made in the character's universe for the sake of the film are usually so off, that it oft-times it strays away too far from the character's unique feel that helped to separate it from that of other superheroes.
Spider-Man's debut featured adaptations in the wallcrawler's world that showed that not only did Sam Raimi & crew understand the character's premise, but also, respected it as well.
