See it if You love Magic and the world of Harry Potter. You like the music of Imogen Heap.
Don't see it if You can't deal with time travel as part of a story or you are unwilling to let yourself be taken into a world of magic.
See it if You love the songs of the Temptations and the Supremes. Want to see talented people sing Classics LIVE w/emotion and perfect pitch!
Don't see it if You don't like Soul Music or you dislike a look at human life in it's TRUE raw form.. with its ups and downs.. struggles..
See it if You love slapstick comedy. You can follow a story where Actors play actors playing characters in a play. "MAKE EM LAUGH" is right
Don't see it if You don't like old school comedy.
