These are GREAT! They actually used to be free (way back, 2 years ago) but it's well worth the dollar. This was the way my boys saw their first movie. We figured that, for free, we could leave halfway through if they got antsy (but they did great, and we've been back several times since then!).
I don't see the titles listed yet, but they're always G and PG, usually 2 movies per week.
