10 Awesome Movies That Fail In The 3rd Act

Jordan Peele's Us had such an irresistible, elementally terrifying premise - of a woman, Adelaide Wilson (Lupita Nyong'o), and her family being assailed by a group of doppelgängers - and after the Oscar-winning brilliance of Get Out, audiences couldn't wait to see what unhinged weirdness Jordan Peele cooked up.

For its first 90-or-so minutes, Us is a deeply unnerving and tenaciously well-executed horror film which succeeds on the strength of its sublimely creepy imagery, Lupita Nyong'o's outstanding performance, and an enduring sense of mystery.

But once Peele lets the deflating cat out of the bag, the film is never able to regain its sense of eerie wonder.

The resolution, that the doppelgängers are clones from a government experiment who've been residing underground for decades, was several steps too ridiculous for many to accept, and paled massively in comparison to Get Out's more inspired big reveal.

Nyong'o still does a lot of dramatic heavy lifting even when the script fails her, but for a film that offered up such a tantalising premise and seemingly had the promise to follow through with it, that final half-hour was a major letdown.
