The movies are similar to what you might see on an airplane. Not first-run but maybe not in DVD yet. I'm pretty sure they were all PG-13 or lower in rating. Obviously they can not control who wanders onto the Lido deck while playing movies.
To us, most of the movies in February were not so interesting. The only one I remember was Oceans.
