If you like this person's taste, follow him or her!
See it if sci-fi theatre appeals to you, if video game culture is interesting to you, or you enjoy watching really strong ensembles of young actors.
Don't see it if you have Gnomophobia (yes, that is the fear of garden gnomes!)
See it if you like history, politics, musical theatre, and/or hip-hop; if you think art should be important, accessible, relevant, and powerful.
Don't see it if you think all musical theatre has gone downhill since "The Music Man."
