I'll re-rate something if I re-watch it years down the line and my tastes have drifted away such that the original rating doesn't reflect my current view of the movie, as happened last night when I re-watched Mission: Impossible 3.
I rated it an 80 when it first came out for reasons I can't fathom now. Maybe it was Philip Seymour Hoffman, maybe it was just so much better than the second one that I overrated it at the time, I don't know. On this re-watch though I realized it's actually fucking awful and adjusted the rating to 20. And threw the blu ray in the garbage as I know I'll never want to watch it again. I've never been much of an action movie fan and with each passing year I find I have less and less patience for their repetitive shenanigans.
I'm scared to re-watch the original Predator movie now - which I remember enjoying quite a bit on release. Probably better to just retain the fond memory and not waste it by watching it again with these more jaded eyes.
