10/10 Audio
If you're a sucker for sound mixing, WATCH IT WITH A 5.1 (or higher) SURROUND SETUP ASAP.
I will offer one negative I have: a negative about this Finale is that in a lot of scenes, unlike GuP der Film, unfocused tank shots don't always have special direction or sound design. I watched them back to back and noticed that a couple tanks just give pop sounds when shooting and its only frontal audio. GuP der Film seemed to make even the unfocused tanks have specific direction. This is like the one negative about this Finale.
I won't describe the scene but you'll know what segment I'm referring to if you've watched: that lengthy segment of uninterrupted surround sound immersion with the fun music was my all time favorite surround experience since Civil War (2024) Girls und Panzer's 5.1 mixes are already top notch, but Finale IV knocks your socks off like no one's business.
This is my second watch, my first watch was with a 3.1.2 soundbar setup, second was a home theater 5.1 multispeaker setup.
