It's Meh.
Yes the realism is very impressive but it means the characters aren't as expressive.
I found myself getting bored quite early on in the film. Apart from a snowy mountain, each scene has basically the same backdrop, so visually it's quite repetitive.
The songs were meh and tbh each time they begun to sing my eyes rolled back as I thought "urgh now we gotta wait another 3minutes for the story to progress"
It's basically a lions go walking film, with the odd 'stampede' danger. Only really got interesting in the final showdown.
It was just Meh. Its a 'just going toilet, no you don't need to pause it' kinda film.
