Haven't watched every animated feature this year, but my guess for CellSpex's annual Worst to Best will top at another Christmas themed movie. Not quite sure if she'd bemoan this year as being one of the duller outputs, though, as she did back in 2011.
Of the 3 Madagascar shows we have, All Hail King Julien stands out with its title and location. Unlike The Penguins Of Madagascar and Madagascar: A Little Wild, this one takes place on Madagascar while the others are in New York through an alternate continuity. Conversely, AHKJ is the only one to not have Madagascar in the title.
