The Honest Trailer points out lots of the faults.
Honest Trailers is frickin' hilarious ;D I was gonna say, "epic level miscast", but I'll go with "epic level mis-moviemaking".
The only magic i felt was unbelievable was
A) all the doves coming out of Caplan jacket and Eisenberger doing that trick with the rain, then disappearing when he fell backwards.
Also better "hypnotism" mind control than Professor X, better card tricks than Gambit, a better teleportation sarcophagus than a Star Trek transporter, and a final reveal that inverted the entire concept of a magic trick to show the audience how it worked before showing the 'assistants', or for that matter, us, the viewers.
I was half just enjoying the Jesse Eisenberg-Woody Harrelson bromance ::) and Mark Ruffalo. The other two Horsemen were irritating.
