Despite the put downs by the other reviewers, I'd say this could be seen as part of the MythArc. Isn't it the same concept as the Black Oil which is a latent form of alien life? It infects and transforms the body of the victim. The aliens in this episode seem to be a different type of Grey, taller but with the same craving for blood due to a compromised digestive tract.
It was a good episode in my opinion and shed more light on the MythArc and the teamwork of Mulder and Scully - Mulder ready to accept the preposterous and Scully doing the spadework, dotting the i's crossing the t's but somehow meeting with Mulder's conception.
I hated the tingly guitar and the Hispanic stereotypes though and it is a shame that it (and other episodes especially series 6) couldn't be played straight but must succumb to the lowest common denominator of the US ratings system.
