While this wasn't a bad episode it was definitely an odd one. The story moved too quickly and seemed rushed. Rachel didn't do a very good job of convincing me she was a wraith let alone a queen.
I was also under the impression that the wraith were untrustworthy and dangerous to deal with. Shepard didn't seem to be worried enough about being on a wraith ship without Todd present. Once again the writing seemed to ignore previous behavior of a character type and made the wraith a lot less menacing. I'm starting to agree with Sci-Fi choice to cancel the series.
