Any time Trek is aimed at being popular rather than having something to say, it really has no reason for continuing.
Most pop cultural stuff has nothing to say, but that doesn't stop them does it?
The business of entertainment just doesn't support the mass-market genre approach of
TNG and that's most likely gone for good. Okay by me - I didn't like that style so much anyway. The future will be smaller audiences for stranger stuff.
Look at cable for the future:
Mad Men, Breaking Bad, Sons of Anarchy, Dexter, Big Love - very specific topics and approaches, not very accessible to the mass market, highly off-putting to many people, but those who like these shows tend to be devoted because they are so unique and there aren't easy alternatives. You want a show about a sympathetic serial killer, you got one choice.
The content is strange, specific and lots of fun for the small subset of the total audience that wants that content. The only frustration is - where the heck is the sci fi in this mix? Skiffy isn't holding up its end of things -
BSG and soon
Caprica are the only shows that fit the model. Other cable networks could step in, like AMC with
The Prisoner, which by all accounts sounds very strange and specific, and people will probably either love it or be bored and confused and wonder why anyone would bother making something like that.
Mainstream networks are hopeless.
Lost is an outlier. The best we can expect from them is
V - an okay premise executed in a very mainstream and not-too-creative way.
People have to stop saying that. "Oversaturation" is made up rationalization. There have been 3 "Law and Order" series running concurrently since 2004. That's in addition to a glut of similar shows and imitators, some of which also have spin offs.
No kidding. How many
CSI shows are there now? How many
Saw movies have been made? Check out CBS sometime - it's nothing but police procedurals and interchangeable sitcoms! "Oversaturation" is such a bullshit argument. Give people the crap they want, and they'll gobble it up and demand more, more, more!
Now, irrelevancy is not rationalization, and is a symptom of a larger problem: crap writing.
Sorry, too many shows survive with crap writing for me to think that's a very good argument, either.
