Re: loads of good scifi going on \"at the moment\"
Atlantis has some good building blocks in place, and could turn very good, it's certainly worth watching if you're in front of the TV
Battlestar Galactica could be pretty good too, the Pilot Mini was pretty good, and took some chances.
Enterprise (spoilers of plot points follow)
The Season premiere looks like it's going to be a 2 parter, involving an alternate timeline with Nazis running Earth, sounds like it might be pretty decent. And that is apparently followed by a 3 parter with Brent Spiner guest starring as one of Noonian Singhs ancestors, revolving around the "Super Humans" that Khan of "Wrath of Khan" came from. (I believe Levar Burton is directing these ones). So Manny Coto appears to be starting on the right foot, might be a good time to give Enterprise another try
