Hey guys, if it was so genius to get rid of the Mandarin because he "never was a good villain in the comics", why was it ever necessary to make Killian The Mandarin too? You're arguing that "he's really similar to the comic book Mandarin" to make him worth of the title, but you also justify the twist by saying that Mandarin in the comics was bland and forgettable and boring and so on. See, doesn't make a lot of sense does it
The whole idea Killian had was to play on people's expectations, which makes them easier to trick because they see what they expect to see. The twist works in two ways because it plays the audience a meta level in similar fashion.
The idea was obviously not to just get rid of the Mandarin and the proof for that is the argument you bring up yourself; they wouldn't have had a real Mandarin in the movie in that case.
