My wife and two oldest boys recently performed in Cross Community Players' Brigadoon. Despite their fears, it turned out to be a really good show. This was the first play for my two oldest (aged 8 and 6), and they had a great experience. I'm very happy that they enjoyed it; I hope that we can make a family tradition out of community theater.
Only problem is, now I have the theater bug worse than I have in the past eight years, since my last community theater play!
There's something about theater, both in terms of performing and watching, that is very different from a movie. There's a connection between audience and performers, and a flow to the performance that really makes a difference.
