I watched it blind- no trailers or anything basically on a whim- and I really loved it. Thought the animation was wonderfully colorful and lively. I especially adored the music and surprisingly Diego Luna's singing particularly the song "I Will Wait" and "I Love You Too Much". I was surprised by how many names were in the voice cast too- Zoe Saldana, Channing Tatun, Diego Luna, even Ice Cube- Cube in particular had me cracking up at his appearance because that was really unexpected. I loved the relationship between Maria and Manolo as well.
I'm curious to see how it compares to Coco which I've read good things about so far.
