Glass 

tl;dr not worth watching 

but let's look at where everything started. Unbreakable a very nice standalone film with a different take on superpowers/heroes was released in late 2000. 16 years after the success M. Night came up with a very interessting take on the dissociative identity disorder in a rather and let's just face it boring setup mainly carried by the phenomenal acting of James McAvoy who single-handedly made a meme out of his character.

The great thing about Split was that even people who did not watch the first installment were still able to enjoy a standalone story and a after all great movie experience. If we take a look at Glass we do not get a standalone film we simply get the final piece of an unfinished puzzle which is kind of frustrating because the puzzle did look rather promising. They gave us the original and also very talented lineup of actors. Bruce Willis as the original survivor David Dunn, Samuel L. Jackson as Mr. Glass and James McAvoy in his signiture role Kevin Wendell Crumb (am I allowed to say signiture role? But then again there is no other movie were he was able to show his talent... and please don't let me start a huge rant about the x-men octology decalogy). Anyways Glass was able to underperform despite the awesome choice of actors (who in my opinion were performing alright... each role was performed with alot of effort and every character felt alive and individual) and despite having 2 decent film as a lineup. As someone who has not seen any of the movies, Glass just felt weird and boring in every way. Sadly for someone who expects a nice ending for a trilogy will also be disappointed. The script just did not manage to combine split and unbreakable in a way to capture the audience. The first hour of the movie felt completly pointless and boring. And it felt awful watching our insane (yup I really liked every single one of them) lineup of actors struggling with entertaining the audience. Mainly because none of them were given enough screentime or dialogues to save atleast a few minutes of the film. In direct comparison to Split were the entire movie took part in the same house (and let's be honest for a moment - the first hour of the film took part in the same room even) and James McAvoy was able to hold the suspense in every given moment. Something that was really missing in my opinion. After the inital boring our we are left with a very grotesque action/mindfuck finish that does not get any appreciation. Pretty upsetting because M. Night did prove to us before, that his scriptwriting and directing abilites can leave you astonished. If I may remind you of some of his earlier works ("earlier" let's say pre Split and pre Glass : 2014ish) The Visit. A horror thriller where two kids visit their grandparents. If you have not seen it yet I highly recommend it because the entire movie theatre was baffled when getting out of the theatre (in a very good way). And I really was hoping throughout the entire movie for the certain "WOW" that M. Night Shyamalan was able to bring out in some of us and that his movies so often embodied. Glass is not a movie I would recommend watching if you are interessting on how the "trilogy" ends ask a friend or anyone who has watched it...or you know don't because Split and Unbreakable didn't really need a sequel(and I stand by my point that Unbreakable was never intended to be part of a trilogy. If Split and Glass were more years apart I would even say that Split was never intended to be part of the trilogy either because that's simply how part 3 feels like: a desperate try on connecting two standalone successful movies.)
