The likelihood that this will be in my top 5 films of 2018 = 100%.
The best parts about this movie are the parts that have basically nothing to do with the premise of this movie. It's one of the rare times when the off-beat improv style that has come to dominate modern comedy is balanced well with the high concept.
A few of the highlights of dialogue:
"Your eyes tell the story, Charlotte."
"What about...a tribe of asparagus children, and they're self-conscious about the way their pee smells?"
"Six-inch ribbon curls, honey. Six.........inches."
