One thing that has remained consistently good about the X-Files is the casting. The guys in this episode really do look like ex-cons. Other than the casting, there isn't really much to recommend this episode. Oh, there is a shot of a sweaty Reyes in a black camisole waking up after a bad dream (with Doggett rather incongruously listening in on her from the next room). Too bad she is still overwhelmed by the role and she gives yet another bleh performance, which is unfortunate since she is the focus of this particular episode.
The initial suspect in the murders is so obvious that we know it can't be him. And as there aren't a whole lot of other characters left alive, it's pretty easy to figure out that the killer must be either the group counselor or the bored detective. So flip a coin.
In the end, the storyline ends up being pretty clever, it would have made a nice feature film in itself. It seems completely arbitrary that Reyes has some psychic connection with the events, but it's reminiscent of a previous X-File episode where the agents discover their past lives, so I'll give this plot contrivance a pass.
