I like the movie but there's a few problems with it. First of all, Jack Nicholson's character is supposed to be perfectly normal at the beginning and then he gradually goes crazy, but he looks crazy right at the beginning of the movie already. In the opening scene when they are driving to the hotel, he looks like he's ready to kill his family right then lol. And Shelly Duvall is absolutely terrible as his wife, this is one of the worst performances I've ever seen in a movie. Well maybe not that bad, but it's pretty fuckin' bad. Overall the movie is still a classic, but if you haven't already, read the book, it's quite a bit different and I think it's much better imo
