I think it's too easy to blame just Hollywood. If anything equal blame, maybe more than that falls on the audience. You can't complain that Arrested Development got cancelled if you didn't watch it. And you certainly can't complain about sequels, remakes, or whatever if you do see them. To be fair, at least with movies, the responsability falls on the individual. TV still works on the Neilsen system. And if anyone remembers a certain episode of Rosanne, they pick podunk towns so they can blame them for America's Funniest Home Videos (not the exact words, but the exact show mentioned). "Original" ideas tend to turn mass audiences off, and mass audience is what they want because somehow a Coke commercial works better on a popular show (pretty sure everyone knows soda freaking exists). I wish there were more things like Better off Ted and Last Man on Earth, but generic characters are somehow more relatable. Not to mention the biggest problem. Those who would love to watch these shows, but can't be bothered to get into them because they know they're going to be cancelled.
Still, I say the worst thing on TV today as far as lack of originality are the crime dramas. And as bad as bad sitcoms are, these are worse. What baffles the heck out of me is that SHIELD gets weird flack for some reason, and in its first season it was losing to NCIS. Also known as "every trope known to Crime Drama show with post-9/11 propaganda thrown in." The show that's trying to make something of itself is the loser, and the cheap "every episode is exactly the same" series is the winner. Yeah. Can also safely say everyone hates Gotham for some reason. I admit, the slow pacing is frustrating, but they're thinking long term and if they do everything at once they won't have anything else. And some of the choices made are a little strange. But I;m sure those who are disgusted by it for some reason love watching CSI's new "Cyber" series which is the same thing, only more how a 50 year old thinks a computer works. Cyber is a suffix best served for Power Rangers or something.
I'm mixed about that. It was clearly given the death slot because Fox wanted to sabotage Futurama because Simpsons was the higher money maker (I'd say similar with American Dad to Family Guy, but AD was never cancelled). But then again, I'd say cancelling the show (the first time) was the best thing to ever happen to it. It got a cult following as a result and eventually that lead to more episodes and those movies. I think the show, including the Comedy Central extension, has had a good run. I'd love to see some continuation in the future, sure.
But none of that could have happened if Fox didn't screw the show. I'd see it lasting one more season on Fox at best. Plus, the last season of the CC episodes had some weak stories in it. Feels like they just ended the series before it got too stale. Really didn't like the Fox Hunting one.
