Uncanny Web-Slinger
Super Freak
For me anyways it's not that the twist ruined the Mandarin. I really knew nothing about the character. What sucked was
1. Before the Twist he was such a great bad guy. There was a real sense of evil there. Then Bam. He really is not what we think. A great character wasted. Second viewing will suck.
2. The guy he turns out to be was far too over the top and goofy. **** jokes and stupid personality ruined the whole feel of the film.
3. The back up / real villain was nowhere near as good or cool as the Mandarin was before the reveal.
Nothing to do with the Comics, just the movie
