Insert "Hello Kitty" into "The Grateful Dead Movie" and you have an idea -- sort'a, kind'a -- of what a short, strange trip this film is! Two cute kitty siblings enter a limbo between life and death, while trying to recover one's soul. There they experience numerous bizarre, occasionally gory, disconnected adventures. There is little dialogue other than word balloons, and most seemingly nonsensical. But this is not merely acid-induced weirdness; there's a story in this imagery that will stick in your mind long after watching it. For those who like Japanese animation and "Cat Soup" in particular, I recommend finding tol's "Tamala 2010: A Punk Cat in Space." "Tamala" features another cutie cat-girl, with a penchant for four-letter words, and a propensity toward violence and freaky adventures. Like "Cat Soup," "Tamala" has fantastic art and imagery; plus it boasts a mindblowing soundtrack.
