The Prestige would be perfect if Cutter hadn’t easily explained how Borden did the Transported Man…

Yeah, like the other commenter said… That’s the point. You’re immediately thrown off of Cutter’s correct explanation due to Angier and Olivia protests that it can’t be that simple, citing Borden’s missing fingers. Naturally, the audience tends to believe Angier over cutter seeing that he’s the main character and he’s not a total piece of shit yet.
