I went into The Prestige not expecting to like it, as I hate all other Christopher Nolan movies (Batman Begins, Insomnia, Memento), but I found this one surprisingly entertaining. As a story involving competition between illusionists, it's very clever, but can at times be too clever. The script is excellent and the acting matches. I thought the camerawork and style did not distract from the quality of the piece, as it did in his other movies. I liked how Nolan was not afraid to tread into other territories than just the main rival magician storyline (I especially liked the part where Fallon comforts the daughter when her parents are arguing). There were a lot of subtle touches and hints of things to come, e.g. the little boy crying about the dead bird, asking why its brother had to die.
The movie is definitely too long; it very barely manages not to feel like an ordeal towards the end. I still don't like Nolan's obsession with nonlinear storytelling because it feels like he's making the movie artificially more complicated so when the dumb audience figures out the timing of each scene, they feel smart and therefore like the movie more. Much of the inherent deception seemed superfluous and could have easily been cut out to make the movie tighter and more engaging. Indeed, a lot of the movie did seem extraneous in general (for example, why was Thomas Edison involved?). Even so, it was a very enjoyable moviegoing experience and is highly recommended.IMDb link: http://imdb.com/title/tt0482571/
