One of the very common problems with student films is that they are "preachy", they say too much and show to little. Contrast that with a scene in "Invincible", where Vince is feeling down and considering dropping out. But then he sees a kid wearing his number on his back playing football.
Boom. Instant inspiration without a single line of dialog.

So, keep in mind that movies are about moving pictures and using those moving pictures to move the audience. By the by, DJTV has a great video on this subject as well (if you haven't realized it yet, DJTV is a great resource).
