Question about the very end (spoilers)
Wait, can a 70-year-old movie even HAVE spoilers?
Anyway, my question is: why did they let Dr. Frankenstein hop on the train and leave at the end of the movie? And why did they cheerfully wave goodbye at the station? Sure, he killed the monster (at least until the next movie), and killed Ygor (again, until the next movie) but it was his fault that the monster came back to "life" and killed several people.
It just seems odd that they gave Frankenstein a hero's sendoff, when he should've been put in a cell. Even without proof of his role in the crime, the least the townspeople could've done is poke him with a rake and warn him never to return again.
