Having just got back from a preview screening (sheesh, the admission fee was high!), I can tell you that Bob is once again wrong about a movie, and I'm sick of his Nintendo fanboyishness blinding him to the fact that this movie is an awful pile of tripe, even worse than the one with Bob Hoskins made however many decades ago.
First off, whose idiotic idea was it to reimagine the Goombas as a triangle-helmet-wearing motorcycle gang, that gets beaten by Mario jump-kicking the helmets? I mean, it fits with the reimagining of the Shy Guys as a terrorist cell and the piranha plants as robotic guards dreamed up by a psychotic botanist-turned-robot-manufacturer, but casting Chris Pine as the leader of a motorcycle gang?!
Sure, the cameo by Bowser in a silhouette (and don't even TRY to tell me that's not who that was, you know which shot I mean) was somewhat amusing, but don't even get me started on the art design of the lab where the tortoises are being engineered on. It looks like something lifted wholesale from the set of one of those Science Is Bad movies they skewed on MST3K.
My verdict: Give this movie a miss.
