First off, this is obviously another politically biased Purge movie that ridicules the white man as dumb and ignorant. Its so sterotypically biased that CNN should've been credited in the opening.
Second, this movie is not scary in the least bit. I often forget that its considered a horror movie. Jump scares are the weakest I've ever seen, the participating Purgers aren't nearly as menacing as in the previous movies, and the overall sadistic demeanor portrayed in the earlier movies is toned down A LOT.
Most of the dialogue is pure cringe. Cookie-cutter banter between stern conservatives and foreigners about who's right and who's wrong. You just want them all to shut up until the next exciting scene starts.
Blumhouse has really gone downhill over the years, just dumping out fluff that lacks real horror substance. Surpisingly they didn't rely on jumpscares in this one, which is why it gets 2 stars instead of 1.
