Re: 1931 Frankenstein....
This makes me think of some superhero films. Much of of we've been getting lately would really have been scaled back drastically or even impossible before. The 1978 Superman was just barely able to get by and even that shows the limitations of the day. Spider-Man and Iron Man and Hulk would have been impossible to do before they were done.
Actually, Spider-Man was done once before. The '70s version with Nicholas Hammond.
And it proves your point pretty well.
What do you mean, ironic?
