First off, I thought the use of Butt Plugs, and Pen!s jokes were not appropriate for a kids movie.
Now. Kids anticipated this movie. Were excited to go. Loved the trailers. We go to movies alot. Probably 2+ per month. They were bored with the movie about half way through. Finally when things started to pick up towards the end did they show interest again.
Theater was maybe 1/3 full on a mid-Sunday the weekend of the release.
