I saw this movie a second time to see how it holds up, so you get two more of my cents... which actually turned out to be longer than I expected, so bear with me.
*Not super important but something I noticed -- Etienne's [the French show-goer who "robbed" the first bank] signature on the card that appears in the bank is noticeably different than the signature he puts on the card Daniel offers him before the heist (in Vegas he ends with a swoop to underline his name, which doesn't appear on the card forged by the Horsemen). Additionally, he folds his ticket stub in half while the ticket that shows up in the French vault is unfolded.
*I also find it interesting that Arthur (Michael Caine) offered Thaddeus (Morgan Freeman) $3.5 million and then wound up with $4 million when the Horsemen cleaned him out. If Thaddeus had taken him up on that offer Arthur would have really been ruined.
*I also for some inexplicable reason realized the Horsemen's last names can be made into the acronym WARM (Widler Atlas Reeves McKinney). I still have no idea why I realized that but my brain wouldn't let it go, so enjoy that stupid tidbit.
*Thaddeus talks an annoyingly large game for a man who winds up not being the mastermind. He delivers a lot of ominous lines; specifically he tells Arthur this con has been years in the making. He's right, but if he can divine that, why doesn't he figure Dylan is the dead magician's son? It's probably part of his egotism that Dylan criticizes at the end, acting like he knows more than what's going on, but it seemed really jarring once I knew how his storyline ended (although I agree he probably wasn't in a real jail in his final scenes).
*Holy Exposition, Batman! I wouldn't have minded if it hadn't always been Dylan asking what was going on because, dude, you know what's going on. Asking Thaddeus about the magician who was actually his father and then making an uncomfortable joke about his death was even more cringe-worthy. It's a good thing I don't have a magic parent's death to avenge because I would have snapped, "I KNOW ALREADY!" after the third or fourth time someone explained something.
*Speaking of uncomfortable jokes, I missed the Tranny Tuesday comment the first go-round. Yeck.
*Apart from him seeing Alma sleeping with the Eye book as mentioned, Ruffalo has one tiny scene where he's absolutely alone -- the morning after the Mardi Gras case wherein he's drinking coffee and popping Aleve in the kitchen. No scenes of him "detecting" or working alone, so I'd say the twist holds up in that respect.
*Minor quibble -- at the very end when the Horsemen are about to get on the carousel, there's a close-up shot of Henley and Daniel holding hands. In the very next shot, nobody's holding hands with anybody, so that point of that shot was...?
So, there was apparently a chance that the case would have gone to someone else, which would fuck all his plans to hell.
YMMV, but I would argue that being on the case was a disadvantage to Dylan. He constantly had to bumble himself, which was advantageous in that he could control how the investigation was being led, but I get the feeling if he wasn't on the case he could have been somewhere else behind the scenes pulling the strings. He still would have been inside/one step ahead of the FBI, and he was already (presumably) monitoring the Horsemen so he could have kept their paths from crossing in other ways. (Or maybe I'm putting too much faith in his abilities.)
Why was she even in the movie? I would have preferred to not have that final scene with them getting together in it. It was not cute or romantic but horrifying.
The ending was kind of horrifying for me too. Here's a guy who's been lying to you literally the entire movie. His life for the past 30-some years has been shaped by plans for revenge. You have no idea who he really is or what he's really like since the FBI guy has been an act. So you choose to... date him? OK. I probably would have put him in jail, but that's your choice. It also seemed to me that Ruffalo played Dylan slightly different in that last scene (less sure of himself, stumbling over his words) and I can't decide if he was playing him as nervous of being arrested/rejected or if he was hinting that Dylan was by nature not much like his FBI persona.
All that said, I do still enjoy this movie. It was fun, and I actually would like a sequel to see what the Horsemen are up to now, possibly with a subplot of Thaddeus and Arthur teaming up to hunt Dylan down for making them look bad (although that's making me think "Ocean's 12," which... no. I don't want that again).
*Edited because typos. :(
