The wife and I caught this last night. I didn’t know a thing about it going in, except it had to do with the Day of the Dead. All I know about the Day of the Dead came from freshman Spanish class, Grim Fandango, and a fifth season episode of Babylon 5.
I think going in blind is probably the best way to see this. I had no idea what to expect, and was pleased that for every character development or plot twist I could see coming, there were three that blindsided me.
If you have to know something about it, I’d compare it to a Mexican Kubo and the Two Strings. Both involved a bard PC as they struggled with the binding (and sometimes strangling) bonds of family.
We laughed, we wept, we will probably see it again.
