Admittedly this is one of my least favorite episodes and in large part it is because, as many have pointed out, that we see Mulder "sleeping around" while Scully is in peril. I would however point out that there appears to be more than a little death wish tied up in Mulder's pursuit of a suspect whose vampire lover and his thrill kill cult exsanguinate anyone she has sex with. Early on Mulder admits to local police to not sleeping at all anymore which may be more than a small indication that his actions don't exactly fall in the "swinging" category.
A better reason to give this episode a lower rating is that Perrey Reeves who plays the central character of Kristin Kilar was not a good enough actress to pull off the part. She somehow manages to make joining a vampire cult sound really boring. And since her belief is the lynch pin around which the whole plot operates, nothing else in the episode works.
