My favorite movie is Donnie Darko because that movie has many details. Each time that I see it I find a new thing or reference that I did not see before.
Also, the film can be interpreted in different ways for each person. And I love it because it makes me think so much about life.
(Use "many" for discrete things like details, trees, pencils, etc. Use "much" for collective things like coffee, wind, or money.)
