I’ve always been - presumably unfairly, I’ll cop to that - slightly suspicious of those cartoons that sit between being for kids and being for adults and refuse to pick either - your Adventure Times, for example. I kind of assumed that’s what I was getting myself in for with Infinity Train, but I was delighted to have been proven wrong by that. In this first of apparently four closed-chapter seasons, we follow Tulip in a happily under-explained fantasy world of a train of infinite cars, each comprising a different universe. The broad hero’s journey approach of picking up friends and enemies and shared goals etc. comes in, but what really works is a genuine sense of humour behind it which never skirts into needless wackiness. More importantly, to me, though, is that it gently approaches themes of depression, of feeling like a burden to the ones who love you, to the seeming need to constantly be in control, without coming across as patronisingly after-school-special. It is warm and open-hearted, with some inventive concepts in a quickly lived-in feeling world. If the remaining (and by all accounts, thanks to the mismanagement of HBO Max, final) seasons live up to the promise of this one, Infinity Train might well be something very special indeed.
