It's not bad at all. I rushed the Friday night performance, got there at 10-40ish, and there was no one there. Got a seat at the very last row. Since there were empty seats towards the front, I was able to move after the first intermission so it went great.
You still can see fairly well from the back row and you can hear everyone just fine.
