I think movies have two main purposes:

One, they show different problems/dilemmas that you need to consider as a human being. Some movies are (much) better than others at this than others, but I think most movies have some lessons (or at least "thinking points"). Even the lamest of action movies usually have some kind of "betrayal" theme, that gets close to the core of being human..

Second, the bringing people together is actually also quite important, both in the small well-knit group and strangers. We (humans) are a flock animal, and shared experiences makes our sense of togetherness stronger :)
