"PS: Why are we seeing those images at the end? Is it only to ridicule the final dud? I could have done without that."
Those images at the end (I assume they're the same as in London, I haven't seen it on Broadway) are there, I think, because the production's central aim is to show the danger of blurring the lines between news and entertainment, and that final clip shows *a reality TV star* whose TV stardom has helped propel him into an office he isn't qualified to hold. It's not just about getting a knee-jerk reaction from the audience.
