Tekkon Kinkreet, a movie with a great artstyle, interesting soundtrack, and even better background work. Based on a manga with the same name from the person who made Ping Pong. If you're seeking an excellent looking show with a somewhat mature vibe and a bit of obscurity to chew on; I would say this is certainly worth a watch. Spoilers will be in spoiler text below.
To begin lets touch on animation, its fluid and almost always happening with little key frame senaniganes. There is CGI used in some panning shots, driving segments, and camera angle changes, but its so well done I can't hate it for that. Its not very often so don't worry about it. One note I do have here - is that the artstyle is in a Ping Pong the animation design, meaning that it not only looks pretty unique, but far more importantly is easier to animate. There is less detail and strict form needed to be taken into account in this style; not that its a bad thing, its just means that extra animation should be expected and I'm glad to see it did indeed do so. A negative I do have in regards to animation is the abuse of motion blur effects, it is very noticable and lets be honest here, it's just a way to save budget by avoiding animating properly. That being said in addition to the extra animation the artstyle allows for, the background artists of this movie really put in a massive amount of work, its spectacular how intricate and full of detail the city is. From the moving signs, the endless expanse of buildings, the las vegas style advertisements, street vendors, theres too much to see without pausing the film, and god do I think that is a good thing. Some might say its a waste of effort, I suppose they might also say the intricate details hidden away in the ceiling corners of a gothic church was a waste of effort. For those who are willing to take the time needed to view them, I can say for myself there was no wasted effort. Its nice to see "too much effort" than too little, such is the standard these days.
Moving on to the soundtrack, it is exceptionally well done and rather unusual which is not something I say too often. Just listen to the first 4 minutes of the first track from the OST https://www.youtube.com/watch?v=WixQfMABnFA
