Rule #1: Always be very specific about your wishes.
Rule #2: After watching this movie, you might want to leave a light on while you sleep.
As a Nintendo and gaming fan, you’ll rediscover your childhood in this film. Don’t listen to the naysayers (who really don't even know what the Nintendo Universe is about), just enjoy some Mario, Luigi, and Yoshi bro time on the big screen, packed with tons of references and love for the franchise.
(And now I want a Smash Bros. movie!)
