I think Nolan struck a decent balance between ambiguity and exposition. The moments that were heavy with "tutorials" were still fun because of the visual effects, like when they were folding Paris. The OP forgets that the Matrix had plenty of exposition too. Not to mention, Nolan waits until the movie is well on its way before he starts to explain the rules of his universe. I think inceptions concepts are more complicated than the Matrix's, anyways.
