Having only recently got into SGA, watching all 4 seasons - to this episode, over the last 2 months, I have noticed a massive drop in plot quality. I was pleasantly surprised with sga and after committing to this show, I couldn't believe how good it was. Season 1&2 where awesome, great story-lines continuing throughout the series made this show a winner, but once the wraith battle kinda fizzled out season 3 slowed down a touch, and then they chopped the Doc & wier - I was gutted.
Season 4 has been disappointing, filler episode after filler episode - until now!! This episode, and the previous, sees SGA back on track, great tactical plotting & integration of characters past. A Sexed-up episode courtesy of Mckay's cute replicator & Shepherd eyeing up Larrins "assets", its nice to see SGA up the ante for the mid season stakes. This is why I watch it!
