I was expecting this movie to be kind of fast-paced but shallow, since most of the actors in it are known more for action films. I was pleasantly surprised to discover that Undoing is a much more sophisticated film, character-driven and emotional, with really strong acting performances and unique visual style. The plot is interesting, although not particularly new or innovative; in fact, the story is very much a throwback to classic noir films. But its enough to keep you compelled and engaged to see the story unfold. I really enjoyed this film.
