This is, so far, my favorite Season. I just ordered the new "slim" version of it on DVD. This will be my first X-Files season set.
I love the following episodes: Beginning, Dreamland, Dreamland II, Monday (Mainly for the waterbed), Arcadia, Two Fathers, One Son, SR 819, Three of a Kind (I'm surprised I like this, seeing as how Mulder's not in it), Field Trip, Biogenesis.
I guess I'm not as taken with The Unnatural as some of you. I may have to give this episode another shot.
The Dreamland Episodes are two of my favorite episodes ever. I can't wait to watch them again.
