In what I consider to be its finest episode, Stargate takes a look at Scifi (primarily movies or TV). I struggle to think of one moment of the ep that was not spot on.

(Other notable moments - hoping for a comp: SG1 as Thunderbirds, (they go through the gate and it cuts the strings of the SG1 marionettes. Puppet Teal'k laughs.); "Young SG1" SG1 as the OC/Gossip Girl/1 Tree Hill. Also a slight riff at BSG (revival series); Resident Evil (Jack's replacement is the only one who survives); Jack's "cameo" (and subsequent riff on SG1 Season 9 ending ("fishing? Who wants to end on fishing?); Oooh! Detective Teal'c ("Indeed.")
