Is it? Have the economics of TV budgets changed to the point that it's no longer financially viable? It seems that the Original Star Trek had pretty darn good production values back in the day.

Terminator - Cancelled
Firefly - Cancelled

Babylon 5 - Outstayed its welcome and new spinoffs- Cancelled.
Star Trek - ditto

nuBSG seemed to have a good run with good production value.

What do you think?

Most of the highest grossing movies of all time are SciFi. Almost all of them are "genre". Why does it seem that Genre TV is considered to be such a poor performer?
