Before purchasing this title from Amazon UK, I had already watched it for, at least, 2 times.
So I knew it was good.
I've watched tons of anime and this one is amazing - very well written with a great story development; realistic and fantastical at the same time. You'll be blown away by the amount of details and the thought behind them. The characters have simple clothes (that change everyday!), but the backgrounds, the city, everything is alive, moving, and believable. You can find complex, real personalities within every face you'll see. The style is very distinctive and unique, without the now-regular big eyed faces that would change the spotlight - since this film is more about what's happening than the shiny looks. The animation itself is very fluid, with either action scenes or daily-life situations. Everything happens for a reason, even if you don't get it right away, and you can expect rage, nostalgia and panic from the little guys on the screen. Expect some funny moments too.
I recommend it to anyone who wants to spend their time with something worthwhile.
One of my top favourites, no doubt.
