Yikes, this truly is bad, in a "Why did my friend bring me to her elementary school son's school musical?" way. A youth revival of this show could work... but these kids are way too young. They can't handle the (surprisingly difficult) score, and were clearly not helped by the clunky direction ( it seems like they were given a lot of line readings as opposed to actual direction).
"...everyone finally shut up, and the audience could enjoy the beginning of the Anatevka Pogram in peace."
