Didn't see any threads posted on this movie, and after watching it last night and discussing it with a co-worker, it's certainly a must-watch for any mystery fan. There's not much you can say without giving much away so I won't go there, but I will say that it's similar to Timecrimes, Primer, and Moon but with a different twist at the end that you probably would not have expected. I could compare it to a TV show, but that might reveal too much as well. Anyway, Triangle is sure to offer quite the mind-bending and cerebral movie experience that will leave you scratching your head and digging up as much info as you can on imdb.
