I too am still with the X-Files rewatch. I'm now up to Season 7, and with Season 6 onwards, it's been the first time I've seen the episodes since they were originally broadcast. So for some of them, it's like watching them for the first time.
It's probably a spoiler, but a vague enough one, but best go as far as Season 6 on your first time watch and leave it there.
