There are a lot of amazing things happening on stage at the Broadway Theatre in the current revival of Fiddler on the Roof: artistry, beautiful singing, poignancy, poetry and a darkness that underscores a bleak time in the history of European Jews. There is also a disappointing lack of joy in a production that is so earnest in telling the hardship and heartache that it forgets that there is a reason why we love Anatevka and are moved by it's quirky denizens: their sense of humor about all things.
