I sat in center orchestra, row D yesterday. No trouble seeing the supertitles or other projections, but because the stage is quite high, it was hard to see some of the action on the set, particularly toward the end of Act 1, when Wendla lies on the center of the stage. The people in front of me weren't exceptionally tall or anything, it was just an awkward angle. Didn't feel my neck craning. For reference, I am 5' 5".
