This one is DIARY OF A WIMPY KID: THE SIXTH SENSE. Just imagine that Greg is obsessed with horror movies and can talk to dead people, and he and Rowley have to battle zombies and break a 300-year-old witch's curse, all rendered in an animation style that seems to be intended to make everything as grotesque and unattractive as possible.
Yeah, I'm feeling a little curmudgeonly today. PARANORMAN is actually a fairly entertaining movie, but I didn't care for the animation and actually thought it might have been better as a live-action movie. The story is pretty interesting, though, and the voice actors (who include Anna Kendrick and John Goodman) do a good job. Despite my quibbles, it's worth watching, I think.
