Has Hollywood... And in particularly the Disney Studio... "Jumped the Shark?"
Yes and No. Complex answer to a simple question. You are a studio head, part of a publicaly traded company. Your studio is given roughly 1 to 5 billion a year to create films and make a profit of probably less than half of that.
*You make several different films and hope that about half catch and make there money back. You make a few independent films or buy already made ones at Sundance or Cannes.
*You make a half dozen bad comedies or romantic comedies and they will pay for themselves then some.
*You make 3 or 4 major tentpole blockbuster films. 1 will pass mustard and be the mega hit that will make you money.
Now of the 3 or 4 major blockbusters- 3 are adapated from comic books, popular novels, tv shows- why? Built in audience. Despite grumblings from the public--- these movies bring butts to the seats and thats what counts for a studio boss. Take LOTR as an example, the book had a large following insuring some posistive word of mouth but it was still a gamble. On the other hand Harry Potter is a no brainer- there will be more butts in those seats than you can handle.
Remakes are not any different than an adapted material, except they are adapating themselves, adapting there best materials because the best already brought butts to the seats and it will probably bring them again.
The odd of an original screenplay bringing the type of gross the studios need to stay alive are slim. Gems occur every year in this field but they are rare and usually loose money for the studios.
So did they jump the shark? Do most people even know what that is? I don't think they jumped the shark at all, Herbie in particular doesn't look like a remake but a revisit and Bewitched certainly isn't taking itself seriously as a remake but also fits the bills as a revisit/rehash.
So long as the biggest grossing films each year are not original materials don't expect remakes to fade away.
I think the phrase "Jumped the Shark" jumped the shark about three years ago. Can't quite pinpoint the actual cause, though.
I blame all the reality tv that makes everybody feel like they can make movies and tv...suddenly industry terms are common vernacular. It doesn't help that half of the terms referring to film are being misquoted.
