Alebrijes are somewhat recent, created in 1936 or so by an artist, Pedro Linares, and they are pretty popular, though I had never seen them associated with the Day of the Dead stuff until Coco. I liked the way Coco handled the Day of the Dead, its representation of the altars people place, with the pictures, food and all that stuff was pretty neat, it's clear they made some research and that they took this stuff seriously (though with the liberty of mixing in alebrijes, which I thought was cool). The Land of the Dead was pretty interesting, and seeing cameos from people like Cantinflas and Pedro Infante was awesome, though I do prefer the way The Book of Life depicted it.
Coco is among my favourite movies from 2017, and I'm glad to see other people are enjoying it. \m/ \m/
