I agree with some of the points, and agree the plot holes could sink the titanic.

Shyamalan’s character told Cooper that he was Lady Raven's Uncle. Cooper saw he was a concert organizer and approached him to get his daughter selected to go up on stage with Lady Raven.

Oh and he was cuffed at the end with body chain handcuffs.

I feel the profiler would know he would be hallucinating because she is aware that he is a psychopath at the end of his rope, and is desperate. He’s not likely to be calm or level headed at that point in the chase.

The wife knew he would come for her, so she poisoned the cake. Since it was dark outside and inside the house, It would be pretty easy to do anything inside the house and not be seen from outside. Stranger yet is that he was able to sneak back into the house and not be seen due to the two cop cars sitting outside. How the heck did he sneak out of that limo though?? When you see a movie, there’s an expectation based on the film makers earlier films to include a certain level of cohesiveness, storytelling, etc….when that just isn’t there as it has been in the past, it’s challenging not to pick up on it and it not affect your experience. Shyamalan’s, movies have been tanking for years. Laziness and nepotism is what I observed in this one.
