Glass is really really good, very unconventional and unique. Unfortunately it was by Shyamalan so everyone is judging it much harsher than they would have otherwise. Seems like a typical film that critics (and audiences alike) will probably bash just because it wasn't an instant classic... Amazing acting, on parts of Samuel L Jackson and McAvoy (as expected) specifically. Very intriguing and unique plot, somewhat more than other Shyamalan films; not just in a twisty way but very much in a structuring way. The twists were good too though, some (one specifically) predictable but others not so much. I like the layering of the twists, reminds me of Upgrade (2018) in that respect. I liked the writing of the characters so much, both those of the new characters and the already known ones. It felt like the three were properly expanded upon and further developed. The cinematography actually distracted me twice, a very neat shot on Glass's crazy-haired silhouette against a light, and one the psychiatrist sitting in Glass' room. It was a nice film to look at. The dialogue was good too, it never felt distracting.
May I mention how Shyamalan somehow was able to make a character with DID that both killed people yet also was capable of being seen as human? I was incredibly worried that Kevin would be just another mistreatment of DID in media but in a heart-wrenching way, they portray him very well. Not realistic in that he, well, kills people... and that he has so many alters, but hey, they actually did DID right. The exaggeration of the disorder actually makes it easier to show what's going on inside a person with DID's head. Thanks Shyammy!
I didn't walk away feeling like my life was changed but I know I will go back to this movie again. This movie is one that can be appreciated in many ways, a jack-of-all trades type deal. It succeeds at a lot of things, and no things really feel weak for the most part.
Also may I add the score/soundtrack was suuuper cool, certain themes and motifs were dope. Keep an ear out for superhero tropes and thriller movie tropes alike, as they will both appear throughout, and often the lines will be strangely blurred... Also the composer threw in a neat little time-signature-jumble piece here and there. Some tasteful 5/8 repetition into what I believe was 9/8 or something mind-messy. Nice to hear a composer capable of theory work, melody writing, and sonic texturing all together. Also a neat thing to point out is the excellent use of volume dynamics, specifically between instruments and tonal textures. The soundtrack works well following closely to the scenes their used in, yet also can serve as an album on its own (in my opinion).
Edit: After reading some reviews it is obvious that critics are defaulting towards the "M Night Shyamalan" disappointment story. Bummer. And nothing they say is really substantial, things about location quite a bit (the part about them going to location x or whatever) but it seems like they were looking at it as either one of two things: a superhero movie, or a crazy finale to the two movies before it. The cliches that Shyamalan avoids made me happy he did that, yet those were the exact things critics complain about? Yet it could have 'hit harder' in a few places but that doesn't mean it deserves to tank in the eyes of the public and the analyzers. It's sad because all this negativity seems sooo misguided. Reviews that put it on the same level as Johnny English Strikes Again(?) and pretty darn close to Predator (2018) (!?) on Rotten Tomatoes? Glass is not some instant classic-type masterpiece, no! But it is a really good movie that seems to be killed by high expectations and people who assume what kind of movie it is before they even see it. Erase your brain of assumptions and such and just... just watch it. You'll have a good time. I know I did.
Oh, and really delve into that soundtrack/score, it is pretty cool.
