Like a lot of things, it started out good, and eventually went bad (like AMC), etc.
I used to enjoy the Friday retro, older B flicks, etc. Now it's cheesy made-for-TV-movies, ghost/UFO/Paranormal shows...and the one I just can't figure out....pro wrestling.
And then there's that annoying trend of misspelling words like "Sci-Fi" (which is a misspelling itself).
Honestly, the wrestling is only one night a week. Yes, it's annoying, but it's not like they're running it 24/7.
In the meantime, they still air plenty of good shows, both homegrown and imported: WAREHOUSE 13, BEING HUMAN, FACE/OFF, HOT SET, ALPHAS, LOST GIRL, MERLIN, etc.
And I confess that I enjoy the campy tv-movies like SHARKTOPUS and FLU BIRD HORROR. If you're in the right frame of mind, they can be as fun as the "older B-flicks" you mentioned before . . . .
(Say the guy who grew up watching the likes of VALLEY OF THE GWANGI and MONSTER ON THE CAMPUS.)
