I really liked the ~first third of the series, quite dark and surprisingly scary especially the alien portrayal. Which unfortunately aren't presented as cool later and from then on look like the Asgard from Stargate : / Still has a few good episodes after that, but once Jeri Ryan joins the show (I don't blame her, but that's where it starts) the "stories" start to feel cheaper and poorly executed, and sadly drift away since then to a series that is no longer so special.

J.T. Walsh was a peerless character actor who passed away far too young. Watch this for him as Frank Bach. And for a nice supplement to 'The X-Files'. Another very good reason: Megan Ward.
