Worst episode this season. Feels like it have been done before, and quite frankly a little silly (this from a big scifi fan...). The writers seem to have troubles with these filler episodes. They are constantly reusing stories. Tapping said it herself a couple of times in this episode. Back to the red thread, thefight with the wraith and replicators!
And to top it off, a really "dawsons creek" cheesy ending! The only good side of this episode was that you got to know the new doctor (the beautiful Jewel Staite, from Serenity) alittle more. Too bad when the start of this season has been the best so far!
