The ending was too much
No doubt it was entertaining, but the ending takes too much suspension of disbelief. I understand they did all these psyche tests on him for several hours, but to know he was going to jump off that exact spot is ridiculous. what if he jumped a few feet to the left or right and didn't land perfectly on the X balloon. What if he jumped off another ledge altogether. They actually relied on that wimpy fake doctor to push Douglas off as a backup plan, but my money is on Douglas throwing him off instead. What if they both fell off together? The balloon isn't saving both of them. It should have ended with Sean Penn bursting through the door and escorting his brother down to the party.
