I went into this one completely out of the blue - not knowing a thing about it, and found a movie that looks at infidelity in a way that I hadn't seen before. Production values are solid, as is the acting, especially by the husband/librarian character. Some character motivations and flashbacks could have been clearer, which I think would have helped the overall narrative and clarified character motivation. Also, I found some of the score to be a tad irritating in spots (intentional, perhaps?), but I enjoyed watching Avalanche unfold.
