While it's literally the same plot as the series, the action and animation are improved (though some action is as believable as a Fast and Furious movie). It has a vibe of watching an eSports match, just with very Moe anime girls.
Girls und Panzer
A feel-good sports anime starring cute girls in tanks. It feels like a war tactics game, like Valkyria Chronicles or somesuch. I enjoyed this more than I anticipated.
