If you like this person's taste, follow her!
See it if You are a child of the 50s, 60s, 70s or know and love anyone who is. Or if you've ever sung a single folk song. Or if you never have.
Don't see it if If you think the House Un-American Activities Committee and Joe McCarthy were doing God's work. No, Y'know what? See it anyway.
See it if You know you love clever and surprising ways of telling a story. Or if you appreciate high energy singing and dancing.
Don't see it if If you're expecting a Masterpiece Theatre style dramatization of Tolstoy. This ain't that.
