See it if you enjoy excellent performances and perfectly-timed ensemble work by top-tier actors
Don't see it if you get annoyed by scenes that can border on the sitcom-y
See it if you enjoy a play that surprises you with every turn that it takes.
Don't see it if you aren't a fan of unorthodox narrative structure.
See it if you want to see one of the most important musicals of this century.
Don't see it if you don't like musicals.
See it if you want to see a terrific performance by Laura Linney in a one-woman show
Don't see it if it breaks your heart to see a great actress in material that doesn't live up to her abilities
See it if you are interested in seeing a drastic, overblown reinvention of one of the greatest musicals ever written
Don't see it if you're not a fan of enormous video projections that dwarf the performers; you enjoy subtlety.
See it if you want to see a show that is nothing like anything you've ever seen. I've seen it six times and will go again.
Don't see it if you don't like sung-through shows.
