A childhood classic alongside other animated TV films, such as Teen Titans: Trouble in Tokyo and Ben 10: Secret of the Omnitrix.
Though there are a few weird inconsistencies between this and the rest of season 6, it's a highly entertaining viewing from start to finish. The feeling of the population progressively being transformed into Senior Citi-zombies holds up for me. Lots of interesting little ideas that feel fitting to the KND universe as well. A definite recommendation.
