Keanu Reeves and Sandra Bullock pair up again in what could be described as the anti-"Speed": "The Lake House", a sweet, relaxed-paced, whimsical romance. When Alex Wyler (Reeves, "The Matrix") moves into an unusual glass house on stilts over a lake, he discovers a note from the previous tenant in the mailbox--but no one's lived in the house for years. He replies and soon discovers that he's corresponding with a doctor named Kate Forster (Bullock, "Miss Congeniality") who's writing from two years in the future. Their correspondence turns romantic and their paths cross in unexpected ways, but when they try to truly connect, danger looms. Though the plot of "The Lake House" sounds potentially static, the movie is skillfully structured and, despite some truly awful dialogue, will exert an emotional pull on anyone willing to embrace the device of the time-travelling mailbox. What the movie really demonstrates, though, is the genuine rapport between Bullock and Reeves; Reeves, though handsome, has a wooden presence--but in his few scenes with Bullock, his stiffness transforms into a palpable yearning. On-screen chemistry is slippery and hard to define, but these two have it.
