I can't believe this thread (and more forums) are not alight with the flames of war.
This movie was a slap in the face to the fans. It's obvious they put almost nothing into this movie. And the post-credits? Without spoiling anything, I have to say this: that final shot is something you see in a bad Disney movie. Not something you see in the X-Files.
Out of curiosity: I know a relationship-esque event happened (maybe even more than once) in the series, but I thought they never made it explicit? Did I miss that episode? Because this movie pretty much throws it in your face, and I was not too happy about that (but if it was made explicit in the series and I just missed it, well then I stand corrected).
The movie still sucked though. As a standalone movie, and as an X-Files movie, it was a failure. And I'm convinced it was meant to bury any chance of another X-Files movie/show/anything.
Which is sad, because what else does Chris Carter have as a claim to fame? Millenium was good, but it sure as hell won't pay the bills or make him famous.
