illusionist, Its more my style of magic. Besides it has Paul Giamati in it so how can you not love it.
OK, Paul Giamatti is damn awesome, but that does not stop the fact that the overall movie was mediocre, as far as motion pictures go. The acting was stiff, the characters derivative--a movie can't survive on a good concept by itself. The Illusionist could have been much better--it could have done more.
Now in the prestige, Christopher Nolan created a very compelling storyline and a believable world so that by the end, he had you reeled in. The acting was perfect since everyone was in a role that fit them.
Because of its ambiguities, The Prestige felt less forced, whereas The Illusionist felt that it had to explain everything (yeah, The Prestige explained some stuff, but there was still plenty that was left up to the audience). In the end, The Illusionist doesn't leave the audience with anything. The Prestige provokes the audience.
