Archer, T'Pol, Reed and Hoshi investigate a planet previously visited by the Xindi and start undergoing genetic changes.
This follows the standard formula of the typical episode where crew members transform into something unpleasant. For me it didn't offer anything substantially more interesting than 'Masks' from TNG or 'Threshold' from Voyager. These episodes never hold my attention because they try to create suspense through the possibility of the characters ending up stuck the way they are or dying, but we all know that's not going to happen.
When they initially transform it's difficult to tell the difference between Reed and Archer which doesn't help. It would have been better if the actors had only their body language as a means to communicate but when the universal translator kicks in we have to watch them behave randomly animalistic whilst still speaking English for the remainder of the episode. Hoshi's weird pose reminded me of the body-language you see on a drunk, angry teenage girl.
On the plus side, Trip Tucker is in command of Enterprise for most of the episode and he does a fine job as always. Also, I am intrigued by the end. It is a pretty poor speech, but does this mean Archer is keeping the virus as a potential weapon to use against the Xindi?
