After finally watching it last night, I can say that I very much enjoyed this one. I thought the writing was very well done for all the characters, especially Tosh. Interesting to note it was done by the author of "School Reunion" from Doctor Who series two. Anyway, I gave this one a 9/10 because I think it deserved it.
Oh, and did anyone notice that Jack was just full of awesomeness for the entire episode?
