Surprisingly good, in a terrifying way

Rating: 8/10 (30 August 2017)

Really good horror and thriller. You'll love it if you liked Shyamalan previous work "Unbreakable". But you might feel uncomfortable amounts of cringe when the movie drops the (spoiler) Shyamalan bomb (/spoiler), twice!
Great performance from all actors, especially James McAvoy did a great job. His portrayal of this unusual split personality disorder is really creepy but also fascinating.
The main actress Anya Taylor-Joy's character was also a very interesting, deep and particular character. We see get to know her as we get the know McAvoy's character Dennis.
The movie overall has good pacing, the plot makes sense in itself, but the conclusion is somewhat unsatisfying. It's not bad, it's just not that great.
See it if you want to see a really good psychological horror.
