(Comcast Movies: All Movies) Tom Hanks (above) as an American innocent, hurtling through three decades of turbulent history, almost sunk by his own sincerity, but remaining pure. It’s a virtuosic balancing act he pulls off, making simplicity not only convincing but appealing. Computerized special effects repeatedly place him alongside the likes of JFK and John Lennon, but never get in the way of the story’s main business - personifying American decency and optimism and keeping it alive. (PG-13; runs through Jan. 4)
