I found it to be an extremely charming and different take on the show. It's certainly not the best-sung production, but that didn't bother me. The music is important here, but the focus here is on the text and and its themes. I found there to be a greater emotional immediacy in this production than any other I've seen. The staging, as expected from Fiasco, is inventive and serves the piece, often very well. The second act does lack the inventive spark of the first half, a fault of both show and production, but it builds to a very poignant "No More" and a humanization of the Giant I hadn't seen before.
Surprised the acting is being criticized; I thought the acting was uniformly very good, with standouts being Jennifer Mudge, Emily Young, and Patrick Mulryan.
For those curious: "Our Little World" and the full "A Very Nice Prince" are reinstated, the Narrator is cut and his narrative lines divvied up, and the aphorisms that accompany the midnights in the first act and the final scene are also cut. Of those cuts, I only missed the aphorisms in the finale - it provides a much-needed transition from the Giant's defeat to the final scene and reprise of "No One is Alone."
"...everyone finally shut up, and the audience could enjoy the beginning of the Anatevka Pogram in peace."
