Hi Barb, I use a site on the web to evaluate movies. It has many critics reviews as well as what audiences thought of the movie. The site is:
www.rottentomatoes.com If a movie reaches a certain score it is deemed "fresh", which is good. If it does not reach a target score it is deemed "rotten" and should be avoided. They are not always right, but I find them to be close to the mark. Good luck with the movies! Hope you enjoy the "Rotten Tomatoes" site.
