I use to do that, but I usually regretted. I read so much about a movie on advance that I often ended up not go to see it at all. The writers point out everything that is wrong with the film, but seldom mentions anything good about one. They also tell many things and even the ending of the movie. Lately I have changed way I choose movies to watch. I read reviews afterwards if necessary. What is very importance to me is that I don’t watch the talk shows in that people discuss movies. And I don’t ask other people how they like of it. Now, I enjoy myself even more.
