When Final Fantasy TSW came out I locked myself in my room for about three weeks out of morbid embarassment. I was afraid people on the street would point and laugh at me for being an FF fan. After finally emerging I watched the movie around 14 times trying to convince myself to like it, without much success for the most part, though I briefly managed to think it was a 3/5 at one point.
otoh I genuinely enjoyed Advent Children. it's basically a middling episode of Buffy padded out to feature length and given great set design, which means it's 6.5/10.
