I preferred the original over Atlantis- just my opinion, but I thought the story writing was a tad better, and of course having McGyver there injecting his quips and humorous comments through the show always makes me smile.
But Atlantis isn't BAD by any means - stacked up next to other SciFi shows that have aired, it's pretty good. (anyone remember "Lexx"or "Cleopatra 2525"? if Not, consider yourself lucky). At least the show has enough interesting characters to compel me to return for next weeks adventure, time and again.
Right now Battlestar Galactica is another fave- great writing, lets hope they allow it to finish up with a logical & deserved ending... unlike the show Farscape, that they aborted for reasons that still mystify me.
And yes, the Stargate movies have been pretty swell, in my opinion too.
