We went into 1980's Xanadu thinking "this is gonna be a bad movie", and folks, we were both very right and very wrong. Is the acting wooden? Is the plot almost too simple? Is the directing middling at best? Yes, yes, and yes. But is the music great? Is there plenty of dancing? Does it have Gene Kelly rollerskating? Oh, absolutely. Unfortunately, the disco-fever-dream revival of 1930s musicals was a still-born genre, one that very few people embraced, but it has definitely has two converts in Mary and Dennis.
