     Do you read reviews after you see a movie? I used to do that, but I usually wished I didn't. I used

to read so much about a movie on advance that often I ended up not go to see it at all. The writers point

everything out that is wrong with the film, and seldom mentions anything good about one. They also tell

us the important things and even the ending of the movie. Lately I have changed way I choose movies to

look. Now I never read reviews before a movie. I read them afterwards, if necessary. I don't watch the

talk shows which people discuss movies. And I don't ask other people how they like of a movie. Now, I

enjoy myself even more.
