Peal Harbor - Bombs Away: WHEN YOU assume battle stations for "Pearl Harbor," make sure you sit near the aisle. You've got three hours to withstand, and only about half of it is war. This is definitely a two-bathroom visit movie. It's not the length that makes a movie good or bad. It's the pacing. Some three-hour movies, like "Lawrence of Arabia," just glide by. But movies like "Pearl Harbor" drag along because they . . . take . . . their . . . time . . . about . . . everything. Put it this way: When a Japanese military officer reports that "the task force" is 320 miles north of Pearl Harbor, we're one hour and 20 minutes into the movie. By then, you're ready to bomb something yourself. Perhaps they should have called this "Bore-a, Bore-a, Bore-a."
