First I thought "What a weird episode" but as it continued I began to enjoy it more and more.
It was a typical X-files episode with the Aliens, bountyhunter and all, but still, it was told through the eyes of another character, another believer.
I missed one thing in this episode though, the comments of Scully on the story, I'm sure she would have had a lot of comments.
At the end of the episode there was a special moment between Scully and Mulder, you could see that clearly thanks to the different shots and the fade out.
David Duchovny did a great job writing and directing it.
