Enjoyable movie undercut by poorly-conceived plot twists

Rating: 7/10 (25 August 2019)

I haven't seen GET OUT yet, so I cannot make comparisons, but I find I have similar problems with US as a lot of disappointed fans of the 2017 horror hit do.
US fires on all cylinders when it's being an exceptional horror-thriller. The home invasion scenes and the dark comedy are brilliant. The characters are enjoyable and the dialogue between them is well-written. Much of the movie felt like a 1980s family comedy like THE GREAT OUTDOORS turned into a nightmare, actually. It was quirky but enjoyable.
However, once the twists and explanations for the bumps in the night come in, the movie starts losing my interest. I think the filmmakers try to overexplain too much and too often. Keeping the dopplegangers' identities more mysterious seems a better option than opening the whole can of worms of their existence and their rather convoluted plan to get revenge on the upper world.
I also agree with the high-rated review which argues that the last twist regarding the mother's identity undermines so much of the movie. It felt like it wanted to shock just for a cheap gasp, not because it was a logical conclusion.
