I just got finished viewing Captives and I liked it A lot. I guess it was Tim Roth's interaction with Ormond that drew me in and stopped me from switching channels. A lot of dialogue was spoken not with words, but with expressions. And the more I think about it, the more I feel the movie kept a constant level of tension throughout. As for believability, I know love can be blind, having been in love myself and that thought, for me, kept the movie alive. I give it a big thumb's up.
