This is perhaps the weirdest season of the x-files. It almost completely changed tone. The production was moved to Los Angeles and it certainly shows.
There were a few more completely random alternative reality episode that were on the one hand funny but seemed a bit too silly.
A few clever episodes were X-cops and the Goldberg Variations. X-Cops though did leave with a sense of breaking the fourth wall in some sense.
The final episode Requiem was really more in line with the mythos of X-files.
