I only really got into the X-Files TV Series from near the end of Season 4 and so only had the horribly out of sequence (and overpriced) "File VHS Tapes" to piece together what occurred up until that time in the storyline which meant I missed out on a LOT of key mythology info and some great standalone stories.
Believe it or not I brought this box set back on release date in 2004 but for whatever reason I never really got around to watching it until a few weeks ago when I started digitising my DVD collection. I have been glued ever since. I found the first series a bit hit and miss but out of the 25 episodes in Season 2 at least 20 of those always left me wanting to go straight onto the next one. There is just the right mix of humour and romance between Mulder and Scully and the episodes looks like they had a bigger budget to play with so were a little more ambitious in the way that they story was told.
My Favourites: Colony, End Game, Humbug, One Breath, The Host, Blood.
Missable: Little Green Men, Firewalker, 3.
