Guardians of the Galaxy Vol 2 is good. It's not so much a sequel but a companion piece so if you liked the first one you'll like this one, and if you thought the first one was lacking something then you may find it in this one.
Anything with Guillermo del Toro’s name attached to it is going to be a visual feast, with a little darkness thrown in, and that’s what animated “children’s” movie The Book of Life is all about.
