I was going to say that just now, lightguy!
The Muny is a huge outdoor theatre, as with their sister "Starlight" Theatres in Kansas City and San Diego. They have to approach things differently, both creatively but especially technically. They have wing space but no fly space to speak of. It's outside, after all. Lighting is limited technically, but also for 8000 seats (no balcony, all on the ground), you pretty much have to hit them with a giant wash of light so they can be seen by the back sections. It's akin to doing a Hollywood Bowl concert (without the giant video screens on the sides showing you the actors' faces). As a result, these relatively close photos look "flat" with no shading or nuance or mood to them. But if they used dark, mysterious lighting (like they did on Broadway, which became SO tedious and dull after awhile), you can't see faces or even bodies at all.
The costumes and sets are also designed for the back row.
Personally? I see more creativity here than I did with the Broadway production. They had no excuse for coming up with such boring "flat" sets and costumes in a theatre that could have easily handled more than just a tilting floor.
