I think because rose seemed like she took some good acting lessons I first felt she might be on it after Chris found the pictures but I guess Chris was blinded by love to figure stuff out I think

I knew the whole time Rose was in on it. She had to know what her family did and she never gave the impression that she thought the other black people were acting weird. If she would have played along more with Chris instead of just brushing everything off, I would have been conflicted on whether she was in on it or not.

Overall, the movie was ok, I don't think it was as good as people are making it out to be. It reminded me of the Stepford Wives.

.....that Rose was probably in on it.
While Chris and Rose were outside discussing things, (it was at the same time the "bingo" game was going on), was when it first clicked in my head that she was a culprit.

I liked the movie, but it started to lose me when it got into the brain transplants. Some of that didn't make sense because it make me not understand some of the hypnosis.

I didn't realize it until she confirmed it telling him about keys, whole the time I was under impression that she is hypnotized as well and parents are looking for some good match for her.

i also had my doubts during the scene where they were talking by the water when he tells her he wants to leave... she played him well!
