X Files 2nd movie. Made it way too late, they had a good thing going with the first movie, but the TV season after it killed the momentum and by the time they tried it again it was too late, and they didn't even address the conspiracy...it was like an episode of the Show and not even a good one.
Now they are talking about a TV reboot, which makes more sense.....if they do it right.
If they had ended the show earlier and then done a 2nd movie a couple years after the first, they might have had a movie franchise on their hands....but....
A Matrix trilogy sounded good on paper, but in retrospect it probably would have been better to leave it at the 1st one, or rework the whole thing and just do 1 more movie.
