These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Awesome Ego: You could make a case of this for most of the characters, particularly the Four Horsemen and Bradley. They're all arrogant blowhards, but the former are so magnificent with the heists and tricks they pull off, and the latter with how he is able to brilliantly dissect their heists better than the law could ever hope, that it's easy to see why. Then it turns that Bradley is not quite as slick as he thinks, while Dylan Rhodes is the most awesome one of all.
Critical Dissonance: Rated "Rotten" at 48% on Rotten Tomatoes but the "regular" folks at Cinema Score rate it an A-. The film's strong week-to-week holds also indicated terrific word-of-mouth from audiences.
Designated Hero: See below. Seriously, in many other movies, Dylan would be the villain, and the Horsemen his pawns. In this movie...that's still sort of the case. There just isn't any hero character to stop him. At least one trick- the car chase- could easily have gotten a lot of innocent people killed.
Designated Villain: Probably an issue that bothers many people who have seen the film. Thaddeus Bradley did nothing illegal and nothing more immoral than expose Lionel Shrike's magic tricks. Of all the people responsible for Shrike's death and his family never receiving the life insurance they were owed, he's arguably the least responsible, yet undeniably gets punished the worst for it.
Even Tressler Insurance and the company that made the safe are arguably in the clear. The former refused to pay money out because the guy in question....performed an extremely dangerous magic trick that predictably got him killed- granted, not his family's fault, but insurance isn't meant to cover nigh-suicidal behaviour; the latter, in fact, did nothing wrong at all- you are not supposed to lock yourself in safes in the first place, and they are designed to not be opened easily.
Magnificent Bastard: Dylan Rhodes. Nobody knew he was really the Fifth Horseman. Even Thaddeus Bradley, who's known for deconstructing illusionists like him.
Narm: It only become apparent on replays, but the final scene between Dylan and Bradley may become a lot sillier when you realise that as Bradley is desperately trying to work out the Horsemen's trick to save himself from life imprisonment (while standing with his back to Dylan), Dylan is squeezing himself between the cell's bars in order to make his big reveal as the Fifth Horseman
Or The Eye really does have "True Magic," and Dylan just teleported.
The piranha trick in the beginning by Henley has some pretty fake looking piranhas there. According to the "Making of" feature, they originally used real piranha, but found that they didn't show up in the shots.
During some of the revolving shots in the Four Horsemen's first magic act, you can see that parts of the crowd are CGI generated. According to the "Making of", some were blow-up dolls.
