played the text base RPG on the ATARI 800

I still have my 800XL, but never knew of any games available for it. I spent over 7 months teaching that damned thing to play poker, and it still cheated in a manner that I had specifically forbad it to do. (Drawing the same card twice.) Thanks for your signature. I've always loved that line, but have been mistakingly attributing it to Toad.
Anyhow, I both agree and disagree with most of what has been posted here. "Eureka" is one of my absolute favourite shows, but it is not SF. It's a very clever comedy staged in a pseudo-scientific environment. "Haven", likewise, is not SF. It's a Steven King book stretched out to a series. No supernatural crap qualifies as SF. I love the show, but it is Fantasy, not SF. Same for "Merlin", "Xena", "Hercules", "Being Human"... (And by the way, regarding the latter, with no offense to the NA cast and crew, the original British version is far superior.)
"Lost in Space" would deserve its own special place in hell if such a place existed. It's not SF, it's not comedy, it's not entertainment... It's as if a bus full of retarded clowns exploded on a leftover set from the first season of "Voyage to the Bottom of the Sea".
I love "Sanctuary", and am a huge "Buffy the Vampire Slayer" fan. The former can pass for SF; the latter is Fantasy (on more than one level for me

).
Speaking of Sarah... after ignoring it completely for over 95% of my lifespan, I have become very fond of "Scooby Doo" shows, both the live action and the cartoons.
"Firefly" was awesome, and the "Serenity" movie the best of the bunch. That sweet little girl on it reminds me of another favourite that died prematurely—"Terminator: The Sarah Connor Chronicles".
Someone mentioned "Misfits". I watched a couple of episodes and hated it. I can't help thinking, though, that it's a ripoff of one of my favourite shows from way back—"The Misfits of Science". That was back when Courtney Cox was unbelievably hot, right after her debut on Springsteen's "Dancing in the Dark" video. Again, though, that show was a comic book brought to life, not SF. Same for the brilliant "Greatest American Hero".
I'm not finished yet, but I'm going to post this now because I'm afraid to lose it in case of a system failure. I'll get back to it.
