I live in California, so most of my theatre-going is in LA. But, anyways, for me, it definitely matters where I sit. For example, I saw Les Miserables, and I had AMAZING seats. I was really close and was able to see every emotion in all of the actors. I don't think that seeing that show would have been such a powerful or moving experience for me if I were to see it from nosebleed seats, or way in the back. Also, being a young person considering a career in theatre, going to the theatre is a learning experience as well. I find it best to learn in really good seats, even if it means I'm going to pay more. Hey, it's all for education
Opera is when a guy gets stabbed in the back and, instead of bleeding, he sings.
