The Infinite Quest is exactly how to do a animated Doctor Who episode. The animation is by the legendary Cosgrove Hall studios (the animation company behind Danger Mouse) and as you would expect, it's as great as any of their other animations.

It just feels like what it is: a animated Doctor Who adventure.

The narrative is wonderfully Doctor Who, zipping across various interplanetary locations everywhere and anywhere on their journey to find the spaceship 'The Infinite' before evil space pirate Balthazar with his pet parrot Squark find it first. Alan Barnes has done a great job; this feels like it could take place within the live-action series of the show if it wasn't constrained by budget. The animation is therefore used well to show a scenario on-screen that would never have been possible within the series.

Simply put: this was too good for CBBC and Totally Doctor Who. A great Doctor Who adventure.
