I liked it. i thought it was very good. almost as good as people said, except for a couple things. The funny bits were not funny at all, except with maybe one exception When he calls the servant lady a crazy bitch after she apologized in the room. They should've eased off of the humor and let it be just a creepy movie instead.
The concept was really brilliant. I didn't see the entire thing with the brain transplants coming. That was genuinely creepy and interesting and made for an intense final 30 minutes. probably the first movie i've seen that took that kind of legitimately interesting twist at a 0-60 speed of 1 second. it made the entire story so much more interesting.
It also wasn't as preachy as I expected it to be, but I honestly don't know why they chose those stereotypes of white people and black people. I don't know of any white people who act like that (bingo, parties like that, dressing like that) or any black people who act like that (the fat guy's type of humor, calling each other "brother" like that, worrying about being around white people or being in the "sunken place" like in the hypnosis, etc). seems like people who don't fall into any of those stereotypes might leave the film with the wrong impression about what it was really about.
also, the scene where the dad was basically representing a slave trader was pretty creepy. probably the best scene in the film. did not expect that, and while it might have seemed to be exaggerated to some...i think that it makes sense considering the family's history with the slave trade and the grandfather's desire to be immortal via brain swaps. they basically represented a neo nazi type of family where the family still practices those cultural things out of a fetish for the past.
the plot could've been done without the black/white aspects to it, though. it might've even been a better film as a result. but then again, maybe not. maybe the racial elements to it contributed to the tension that created the final 30 minutes of awesomeness. *shrug*
