-I really didn't like the flashback in the first episode. That really should have occurred in the first season. Introducing Desmond in the flashback and then revealing him to be on the hatch in the same episode really killed any type of mystery or suspense. It was the complete opposite of say Michelle Rodriguez's character, who was introduced briefly in S1, and when you see her in S2 you're like whoaaa (although in S1 when she told Jack she was in the tail area of the plane I knew she'd show up on the island eventually).
-Also I wasn't a fan of the long, drawn out, repetitive reveal of Desmond from multiple POVs. That took up what, 2 and a half episodes? But things definitively got interesting once he started talking.
-I fucking called it: human experiment. But then again, who knows whether the tape Desmond had is actually real. Even if it isn't I'd say this qualifies as a human experiment or something like that.
-God I wish Jack didn't push the button
-OTHERS FINALLY. WTF @ that big black guy.
