I went last night.
It was a lovely evening in the park, weather-wise. A nice breeze kept the audience cool throughout the three-plus hour performance. I spotted Liz Smith and Donald Moffet in the audience.
The show is a complete mixed bag. There are moments of complete and utter brilliance, and then there are times when it drags or is even just ridiculous. The music by Jeanine Tesori is a constant delight. It's summery and beautiful, and really compliments the songs. The onstage band is top notch.
As Mother Courage, Meryl Streep is quite wonderful. She is both tender and tough as nails, and her singing voice is very strong. She has a lot of earth mother qualities.
I was shocked at how well Frederick Weller sang. His role as Eilif, Courage's oldest and bravest child, isn't extremely well-written in this adaptation, but he makes the most of it. Alexandria Wailes is excellent as Kattrin, the deaf and mute child. I cannot remember the name of the actor who played Swiss Cheese, the stupid but kind child, but I did like him.
Kevin Kline, as the Cook, seemed very disinterested in the precedings. His singing voice also seems to have diminished since his salad days in On The Twentieth Century and The Pirates of Penzance. Austin Pendelton as the Chaplain stepped on nearly every one of his lines. I was embarrassed for him.
The standout was Jenifer Lewis's Yvette. She knocked it out of the park (literally

) with her one big number, and commanded the stage whenever she was on. Girlfriend looks fabulous too.
Loved the set and the costumes. Needs to be trimmed...at three hours and fifteen minutes, it really drags a lot.
"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."
