This is the first feature film for Peter Howitt, and he approaches the task with unimpeachable aplomb. The script is shrewd and inventive, combining wit, romance, and intelligent melodrama into a crowd-pleasing whole. Sliding Doors grants more than just a good time at the movies, however. For those who are so inclined, its central theme offers an opportunity to ponder some of the more philosophical questions about the workings of the universe — all while having a good time. — James Berardinelli
