Tim Burton scratches a long-standing itch with Frankenweenie, his third light-hearted stop-motion horror after The Nightmare Before Christmas and Corpse Bride. Returning to a short film he made back in the 1980s at Disney before he was fired, he has logically expanded the story out to feature length without compromising the original’s charm. It’s as Burton-esque as they come, which means there’s nothing here that will convert those who haven’t got on with his characteristic preoccupations with gothic gloom and fairytale horror in the past. But for those who do, it’s a true return to form. After the ravishing but hollow Alice in Wonderland, the director’s journey back to his roots sees him rediscover the simple joys of a childhood obsessed with darkness.
