I've seen many films that I would give a BOMB rating to but each one of them had at least one good thing in them. That's why I don't leave a film early. S.I.C.K. was clearly one of the worst films I've ever seen but the ending really blew me away so..... I'm glad I sat through the torture...
You did good because most people walk out of this one before sticking the tape in the VCR. :D I've never walked out of a movie or turned one off but I was close to doing so on 10.5, which I watched earlier in the year.
