Aye, the whole shield deal was neat.

And the transport closets...although that begs the question, what did the Ancients use for closets then? Considering their wardrobe, it seems like they'd need a pretty big one.

The big dark thingy was a neat baddy, though I thought the solution was too similar, well, the whole plotline too similar to SG1. Instead of a dark force possessing people, we have a dark force possessing power generators

I sort of wish they'd mixed up the roles a bit more, it seems like a copy of SG1, except McKay taking Sam's role and Weir taking Daniel's. But you've got the same insubordinate leader and the outsider/warrior. Although, granted, Teyla seems to have more experience than him.
