If the best movie theater is the one that has the best new movies, then this 10-year-old multiplex offshoot of the Uptown--run by the muscular Landmark Theatres--is clearly the best. In the past year, owing to the bargaining power of its parent company, the Lagoon has played exclusive host to no small number of "specialty film" essentials (like 'em or not): I (Heart) Huckabees, Bad Education, Before Sunset, Vera Drake, Tarnation, Control Room, Dogville, The Brown Bunny, and Primer, to name a handful. Sometimes, inevitably, the corporation wins--particularly if it screens The Corporation.
