I love earlier works of M Night Shaymalan, that is why I got very excited for OLD.
But.
1. It is the worst piece of writing you will ever see. I mean ever. It's like some 5 year old kid wrote the screenplay. It is horrible, simply horrible.
2. To call the ending (climax) as an awe-inspiring twist ending would be disrespecting movie endings. It's the stupidest thing you will ever see. It's like, couldn't he think of something else.
3. And why is he obsessed with his own roles in his own movies. You will see M Night as one of the main characters and you will cringe.
OLD movie is by far one of the worst films you will ever see.
