...from the caviar, salmon roe, and chicken eggs to the fish climbing out of the sea. The metaphor here is beyond Dr. Seuss style, you can't miss it.
As a sci-fi concept, this would have been amazing. If it were my movie , I would have cut the first scene completely (playground, it added almost nothing, the little it did is a spoiler), and then got more into the "clinic." But it's not and so it went from horror to horrible slow and steady.
One thing I'll give, the suspense sucks you in. It's so completely offensive and shocking you want to see where it's going. It's definitely a train wreck you can't look away from.
