The finale was great, although it left me depressed, as there won't be anymore X-Files.
Also, I felt so sad for Mulder and Scully - I don't think they got the details about extraterrestrial life that they wanted all along, and it seems that they finally just gave up. Very sad. But I'd really like to hope that those two finally got it on in that hotel room! After 9 freakin' years, they better have started banging!
I didn't start watching regularly until Season 7, which was very good IMO. 8 was cool, and I've really missed to much of 9 to judge it.
I watched a few times before season 7, but not usually. I was brought into the show season 7 when I realized that Scully is pretty damn hot!
