'Kung Fu Panda 4' is much like its predecessors for me, I'm cool with them but they don't hit any deeper than being just solid movies. I had to watch a recap of the previous entries, naturally, and didn't remember much, aside from the cast and main characters.
I reckon I'll be saying the exact same thing in X amount of months about this one, that doesn't necessarily mean a film is bad though - because this release isn't. The voices we hear are perfectly satisfactory, from Jack Black to Awkwafina, Viola Davis (the best, away from lead) and the rest.
The music here is good. There is one piece of the score, which is heard a couple of times and during the end credits, that must be a homage of sorts to television show 'Dexter' - weird connection granted, but it sounds practically exactly the same to me.
On the note of the sound, I enjoyed Tenacious D's rock cover of "...Baby One More Time". I listened to it an embarrassing amount when it first released alongside this movie, the video was admittedly part of the reason why - I'm always a fan of seeing film casts in music videos.
There's a decent story told, alongside nice animation. It'll no doubt be forgettable to me personally, but I can still acknowledge it as something that I deem passable.
