I am not good at reviews, but this show deserves more reviews than it has, so here I go.
If I had to imagine what one of my favorite anime would be, it wouldn't have been a surreal post-apocalyptic fever dream with casual 'slice of life' anime vibes, but here we are.
Ever get that feeling when you're watching a new anime that you're witnessing the beginning of something special? Train to the End of the World gives me that feeling, and I haven't felt that in a long time. This show toes an interesting line because I'd say at this point that it's still fairly family friendly - but there are a lot of dark undertones, the most obvious in the first episode being the bloody handprints and bullet holes in the armed caravan vehicles. The art, animation, sound, voice acting - all are superb. Practically every scene in the first episode would make for a great desktop background.
It is dialogue heavy - like Monogatari levels of dialogue heavy. All of the conversations feel natural and have great flow, and I think they are important for establishing the atmosphere the show is going for, but I know people that cannot handle that. If there were any reason to dislike the show this would probably be it.
I'm very interested in seeing how this goes. There's a lot of potential for it to go to a very dark place - the clues are certainly there - but even if it doesn't I'm still on board.
