Half of a really good movie...
I really enjoyed the first half of this movie and the issues presented. Once they went to the purge party, the whole movie tanked. The scenes at the tribute dinner were beyond ridiculous.
Stiller and Watts and Grodin and Chloe did their best with what they were given. Part of the problem is that I really disliked Adam Driver in another movie (This is Where I Leave You), and I allow my total distaste for him in that movie to carry over.
