Interesting sidebar: I accept the distance and angle more in a musical.
I don't find this surprising. Musicals (at least your average big Broadway musical) often draw the material out; as such, distance and angles feel less important. Most plays draw the audience in, which can be hard to do if you feel like you're a football field's length away. It might work for a broad comedy or a farce, but I don't think I'd want to see Long Day's Journey Into Night from the top row of the Shubert's balcony.
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
