X files was great when it started then I am afraid I lost interest and so it seemed did they, however it was always worth tuning in to see Gilly Anderson!!!
Now 24 and The West Wing have been the best things on the screen for a long time.
The X Files was good all through seasons 1-7.
By season 8 David Duchovny did half a season, and the show definitely got weaker with Robert Patrick being introduced to become Scully's partner. Don't get me wrong, Robert Patrick is a brilliant actor but his character, Agent Doggett was just annoying.
The final episode of Season 8 where both Scully and Mulder find that the baby is theirs, could have been the perfect ending to a great series.
...but then the show was renewed for a season 9 which was a complete piece of shit and absolutely unnecessary.
