Movie, Yes or No?

School is winding down ... whew!  Since our state test is taking the place of exams, we aren't giving an exam next week.  That means there is a 2 hour void to be filled.  Do you ever show movies in your math class?  I know at some schools showing movies is a real no-no.  That doesn't seem to be the case in my current placement.  But I have mixed feelings about "just" showing a movie.

I'm trying to reconcile showing a movie next week.  Can you help me?  Any suggestions of what to show?
