I’ll say this about the last two seasons: they’ve left me with the urge to rewatch Seasons 1-9 again, if only to work out what my personal canon really is. Don’t know if that’s bad or good, but there you go.
I worry that I would ruin my memory of x-files if I rewatched it. I fear the alien storylines are painfully dated, and probably even the monster of the week (which we’re always my favorite) probably haven’t aged well.
