I'm really digging the mystery theatre series. In the past few months, I've enjoyed Agatha Christy's "The Hollows" (a single elaborate set, with a large cast) and "Our Man in Havana" (with sparse but fluidly changing sets and actors playing multiple rolls).
A play is about 3 hours with the intermission, so it's a bit more of a slog than going to the movies. Two reasonable seats in the middle of the theatre are just north of $120... worth another go if you ask me ... just check out the website to see what's on and when...
