Watched "One Flew Over the Cuckoo's Nest" for the first time this weekend. Man, that's a movie that stays with you for a while.
Not sure if spoiler necessary as most people have probably seen it.
Completely changing tack, I also caught the "Poltergeist" remake and the gothic horror movie "Crimson Peak". The new "Poltergeist" was a completely unnecessary remake and it sucks. They changed the story enough to just not make sense. I had to go back and watch the original to cleanse the memory.
"Crimson Peak" was okay. Just really, really sloooooooooow. Plus, you figure out the twist almost right away and are mostly just watching the clueless heroine bumble along.
