Singlehandedly saved Season 2.
And now to discuss what was wrong (is it any different ever?)
I think on 1) above, maybe after a while they "trusted" them and needed the PC's networked, or it used it's U8eR WR@I+H c0mpu+0r VIru$ 1337ness sK1llZ to haxor a PDA or something (with wireless), and invade the other systems.
2) I would have had them being hard copied, screenshots and printed, or pictures or anything.
3) Yeh, but I suppose the choice between "Help this wraith" or "50 hive ships a few weeks" I'd probably choose "Help this wraith". Well, if it was reality, I'd just leave and nuke atlantis, but then we'd have no show.
4) Yep, but I guess thats where explanations of 1) come into it.
And honestly, teyla needs to go. Ronon has shown up and become a better character in a third of a season than she has in 2 full ones. Especially that she won't be the "love interest". Sora, Cadman, Super Ford, off the top of my head, could probably be better.
Good Moments (among others)
Asgard. He is cool.
Beckett and Zelenka with the Wraith.
