Is this a good thesis about the film guess who is coming to dinner?

The 1967 film, Guess Who’s Coming To Dinner at initial viewing shows that racial relations have come a long way, however, close scrutiny of the film reveals that racial prejudices are very much alive and they represent a microcosm of societies attitude towards interracial relations.

This is one of the very best places I've seen online to help students write good thesis statements. It shows you sentences that aren't thesis statements and how to turn each one into real thesis statements.
Thanks. Better?

Are you trying to use a 46-year-old film to prove what's going on in today's society?
