tbh I don't think MNS is a very good writer or director. He has some great ideas, but lacks the skill to weave that into something entertaining throughout. He's not bad per se, but I'd put his ability on par with someone who makes movies of the week on Scy Fy(is that how they are spelling it now?) but he has a much bigger budget.
Haven't seen Glass yet, but I'm sure I'll see it someday. Somehow all of MNS movies I wind up seeing by accident anyway, like on a plane/hotel/or it just comes on tv.
