It's not a review from a big newspaper or anything, but I like what this blogger at Rotten Tomatoes has to say about James:

Kin to the rest of the unrivaled cast, James McAvoy as the legend's assistant, Valentin, is wonderful, managing to convey naiveté, wonder, awe, erotic awakening and divided loyalties at once. His facial expressions are a meal by themselves, an entire menu of tics, sneezes, whiffles, perplexity and tormented delight and anguish.

Now here's someone who gets it!
