Re-writing the scripts to Spiderman Version One [1] does not take much.
Those that have read the comics can decite what is more realistic than those that want a different outcome etc.
Basically... I have not rad the original... I do not know what could have happended in the series... but... if they differ,
the storyline point of view from the person percieving the outocme could be altered.
I am not sure what the differences are, but, I can tell that the producers want more than what is identified by the comic series.
