If you haven't already guessed from the title, the Teenage Mutant Ninja Turtles are back in a new feature-length cartoon. While previous Turtles movies were live-action efforts, this new adventure employs CGI animation - presumably in an attempt to appeal to both ageing fans of the original 1980s comics and a new generation of kids. Writer/director Kevin Munroe here tones down the turtles' usual pizza-munching comedy in favour of something slightly darker and less camp. A routine plot about an army of monsters terrorising Manhattan allows Leonardo, Michelangelo, Donatello and Raphael to do their ninja stuff, while showcasing state-of-the-art visuals and supporting vocal work from the likes of Sarah Michelle Gellar and Patrick Stewart. It's not quite as grown-up as it wants to be, but it's still a polished revival of a franchise that many thought long dead.

After the defeat of their old arch nemesis, The Shredder, the Turtles have grown apart as a family. Struggling to keep them together, their rat sensei, Splinter, becomes worried when strange things begin to brew in New York City.
