This may not be M. Night Shyamalan's worst movie, though it's surely his most disappointing.

You have to admire the nerve of Shyamalan for attempting something like this-and indeed, for choosing Glass as the title for a film so unashamedly non-transparent.

With a movie jumping from character to character so often, it just didn't have flow or pacing or tone.

Shyamalan brought something new to the table that is not quite like any other superhero film. His use of the hero, the villain, and the outer forces of power has been brought to life wonderfully.
