Canada – America’s cold, remote neighbor. Seems its romantic comedies are a little like that, too. “Chaos Theory” (2008) is actually a very good Ryan Reynolds vehicle. He gets to play a whole range of emotions as a wedding-day dad imparting wisdom to a cold-footed groom, using his own marriage as an example. But instead of the artistic safety of American-style, cinematic tentpole commerce, this film is edgier, angrier and sadder. But also wittier and with music designed to speak to the story rather than to sell the original motion picture soundtrack. A little harder to love, but still a keeper.
