I think this episode lacks among other things, a strong interaction between Mulder and Scully. Looks like their partnership was in the background the whole time and the very far-fetched plot was more important.
Astral projection is quite interesting, however, I didn't find it that way in this episode. Maybe if they had moved the whole plot outside the fort into the city could've been better. I guess the only one who deserved to die there was the General because he is the one being responsible for putting Roach into that situation. Revenge was a strong motive, but still this just looked like a filler episode.
