There seems to be a lot of difference between the different sci-fi channels, do you have the wrestling on it in the UK or was that America? Thankfully it's on another channel in Australia.
It's usually pretty dire over here as well but there's the odd bit of watchable TV. Haven't seen Lois and Clarke on it yet, all the Star Treks (barring the original), Buffy, Angel, Charmed are on pretty much constant rotation. Recently they have been showing the 80's series V which was a bit of a laugh, I liked the first few series of X-files and Jericho has just started which is cool because I missed the last of it on TV before.
The movies are usually disapointing, they had some ok ones on before like Tremors etc then this month its 'ALL NEW MOVIES' meaning straight to TV CGI rubbish. I started watching Komodo vs Cobra which was just horrible and I haven't bothered with any of the others. I just wish they'd do a run of older sci-fi movies, luckily the ABC often shows them as late night movies things like The Incredible Shrinking Man, Them, Invaders from Mars, The Day The Earth Stood Still etc.
