Tired bitter Mulder versus smarmy is not cutting it for me, Anderson just looks like she is going though the motions.
Some of the effects, esp. the Roswell recreation in the 1st episode were pretty nice, but all in all, this foray 15 years later is luke warm at best.
The appearance of the Lone Gunmen in that "psilocybin" trip went by so quickly I had to re-watch the episode On Demand to see if it was really they.
