See it if Having seen every NYC production of Sweeney since its original opening, this was by far the best. It was Sondheim's favorite, too.
Don't see it if You don't like Sondheim (impossible to imagine), suspense or counterpoint.
See it if you love re-imagined works. One of the best! Brilliant in its concept and execution. This is a Sweeney that will creep you out.
Don't see it if you expect a conventional production. If you don't like Sweeney start with this won't help.
