Lastly, I must point out some things about the Frankenstein Monster.
In the original story by Mary Shelley, Victor Frankenstein was a college student studying biology and medicine, and eventually, he did achieve the creation of life.
As the movie shows, the thing he creates is very large (the doctor considers handling larger body parts easier than handling small ones). But, he was actually a fairly attractive thing, by human standards. He even had long, dark hair, if memory serves. There was no bullshit about bolts in the neck and a flat scalp.
He did study Christian religion, and was a very emotional and psychological being. But he is never referred to as Frankenstein in the original work; he is called the creature, or the monster. Van Helsing avoids this mistake, and calls it Frankenstein's monster. Very good!
Anyhow, I suppose that they had to do what they did for the movie's purpose. Frankenstein created the monster all on his own (there was never an Igor, or as the original version of the film called him, a Fritz). The secret of bestowing life isn't even in the book. The monster was terrifying to Frankenstein, and he went slowly crazy, trying to cover up his monster for several years. It tries to follow him and to approach him civilly, but Frankenstein eventually ends up dying of some disease in the North Atlantic; he didn't die in a windmill fire. Frankensteins monster eventually made its way up to the north pole, where he destroyed himself with fire.

Okay, enough Literature Review. I just wanted to present what I knew.
