The Children's shows are just about an hour long. Bunnicula, the one I am currently in running until 11/25, runs at 45 minutes.
The shows are usually under 2 hours... It is hard to keep a person's attention for longer than that no matter how good the production is...
The will depend on the show. The "adult" shows usually range from 1.5-2 hours. I don't know about thr kids shows.
