This adventure comedy, the first CGI animation feature specifically designed for 3-D, would have been more impressive if most of its images weren't so drab. Its story about three young flies who hitch a ride aboard the Apollo 11 is meant to inspire, and the flight and moon-landing sequences make good use of the 3-D format. But the little heroes and their families are surprisingly ugly, with faces resembling skulls, and the colors are so faded and muddy the movie feels tired and bungled. Ben Stassen directed; with the voices of Christopher Lloyd, Kelly Ripa, Nicollette Sheridan, and Tim Curry, and a live-action epilogue by astronaut Buzz Aldrin. G, 89 min.
