Couldn't Lang have eventually found a pretty intact body, thius avoiding all the stitching? Why not just find one with minimal repairs needed, and just reanimate it? I think because Lang wouldn't be able to have the illusion that he was creating life, rather than just restoring it.
That's my problem with the Frankenstein idea. Frankenstein doesn't "create" life. He couldn't "make" any of the organs or design a nervous system, etc, if his life depended on it. He just takes what God or nature created and jump-starts it. And he keeps frequenting "Criminal-Brains-R-Us" because of the big discount. (I understand they're online now...

Some people die from blood loss. Patch up a bullet hole, supply new blood, wait for a lightning storm, and voila. Sure the brain gets damaged by oxygen loss, but I'm sure it gets pretty damaged from sitting in a grave too. Well, best not to question too closely I guess. And I guess I shouldn't be telling Dr. Frankenstein how to do his job. After all, I'm no mad scientist, and this is his area. He doesn't come to my place and tell me how to be a sarcastic medical shut-in, so I shouldn't mess with his business either.
