I mean, you probably won’t get cancer from watching it or anything, but M. Night Shayamalan DID make one of the characters a movie critic who is explicitly written to represent how stupid and hubristic movie critics are for daring to judge another person’s creative work.
Also Shayamalan himself plays a genius writer whose opus is literally destined to save humanity.
I kind of got the impression he was working some issues out in that one.
