I like non-musical plays better than musicals,. though. A musical has to be pretty amazing for me to like it, something like "Les Miserables" or "Miss Saigon." I am not a fan of the campy musicals like "Oklahoma" or "Grease", etc.
It would be hard to find a musical I didn't like and I love plays but local theatres can be a total hit or miss. When it's shit it's almost painful but when it's good I can't think of many better ways to spend a couple of hours. My least favourite form of performance art is dance, everything else is on my way-cool list.
