These are the lamest of the lame.
The episodes that all regular viewers hate with a passion.
A chance for the viewer to see all of the series highs completely out of context.
A chance for the story writers to take a mid-season holiday.
A chance for the producers to save a few quid.
Imagine my surprise when embarking on a Stargate marathon, by the end of Season 2 there have been no less than 2 flashback episodes. Is that a record? Or do they have one each season?
