-"Each bunker is a completely sealed environment. Nothing gets in. Nothing gets out." If this were a sitcom, they would get locked in.
-Lot of talking this season.
-Suspicious deaths, etc. etc.
-And Jack gets locked in. Seriously. Did anyone not see this coming?
-And, of course there's a bomb.
-Jack's mentor doesn't really plan so well. Of course you put the bomb next to the door and hide under the floor.

Not exactly a highlight of the series . . .
