Saw Inception last night, directed by Christoper Nolan (Memento, The Prestige, Batman Begins, The Dark Knight) and starring Leonardo Di Caprio, Joseph Gordon Levitt, Ellen Page, Tom Hardy and many others (even Michael Caine).
Put simply, the technology exists to join someone’s dream, and whilst in that dream, steal secrets if you’re good enough. Leonardo’s character is this best there is, but he is hired to implant an idea, rather than steal something.
To be honest, that’s as much as I’m going to say about the story, as it is something that should be allowed to unfold with you knowing as little as possible up front; we’re way beyond spoilers here 
The film has been incredibly crafted, and I don’t mean the actors’ performances or the special effects, both of which are excellent. The story is layered well, and covers a very important strand of Caprio’s character’s past. No-one’s character is one dimensional (although Michael Caine is only in the film briefly, so is not given much chance to evolve). Cillian Murphy does well in the film, I really felt his emotions over the relationship with his father, but again, I don’t want to give anything away.
In short, see it, I recommend it highly with 5 stars.
