Kate and Leopold's massive dump on the concept of time travel was a pretty good start, but The Lake House perfected the art. With an omniscient terrier as cosmic referee, Keanu Reeves and Sandra Bullock, separated by two years, engage in a by-mail contest to see who can use their time-traveling mailbox least creatively and do the least good with their incredible discovery in this paradox-riddled puke stain on the fabric of time and space. Soon, the downright naughtiness of using such a scandalously obsolete mode of communication sets both of their hearts afire, and they decide that, continuum be damned, they're gonna find a way to be together! Amidst all the USPS-paced romance and action, will the two of them unlock the secret of the lake house and its incredible time-travelling mailbox?
