I finally had a couple of hours to devote to Girls und Panzer der Movie. Quick reaction: If you liked the original series, you’ll like this. If you found the original too implausible to enjoy, this is no different. For those who haven’t seen the original: if the idea of watching high school girls engage in the recreational equivalent of war with real WWII tanks sounds like fun, check out the series here. If you like it, then track down the movie. You can watch the movie first, I suppose, but it will make less sense and you’ll miss the significance of the various characters’ actions. I don’t have time to write a proper review, but there are reviews here and here (beware: the latter has many spoilers that aren’t hidden).
As Steven guessed, one of the highlights for me was a lively Finnish polka with kantele and accordion in the soundtrack. The movie’s makers didn’t pick the tune at random; “Säkkijärven polkka” has a little history behind it. To make Steven happy, I’m placing the tune below the fold.1
