There is a rule of thumb at our house which pertains to selecting which movies to see, which has stood the test of time. Perhaps it may help you as well.
As a rule, the better the trailer the worse the movie. The 3D trailer for the Christmas release of The Great Gatsby was released recently. Have you seen it? It looks and feels like the greatest beer commercial you've ever seen.
For better or worse the trailer corollary doesn't hold true. Bad trailers derive from bad movies.
