Wow, this is me watching this show for the first time in 2012.
Bummed it got canceled. Anyway, I agree, even if it is 4 years later, lol
They are all guilty. They caused so many problems. I never like how they don't really seem to feel very bad. Gee there goes another planet full of humans thanks to Atlantis. Whoops, creating half human guy Michael who ruins planets and is a scary mad scientist killing humans and children and babies. ( remember that sucked dry baby one of them picked up and tossed back on the ground, that was NOT a doll.) They just do whatever they want. Even Dr Jackson caused all that trouble when he found the lost lab and killed a bunch of people by causing exploding Stargates. They seem too cavalier and casual about it all. It bugs me.
Also I hate flashback episodes on all shows. It seems very lazy to me, like the writers needed a break. Boring to watch stuff I already saw again.
