Poorly acted by almost everyone. Given the number of high-quality stars (for better examples, see Death Becomes Her - Bruce Willis, Changing Lanes - Ben Affleck, The Man Who Wasn’t There - Billy Bob Thornton, Ghost World - Steve Buscemi), such a low standard is impressive.
So gung-ho you can barely watch at times.
A ridiculous plot. Deep-core drillers are hired by NASA to land on an asteroid in space shuttles and blow it up with a nuclear warhead?
Unbelieveable characters - Frost, played by Ben Affleck, is this only one who seems to have his feet on the ground, and his part is so lacking in depth it doesn’t make much difference.
If the film didn’t take itself so seriously it would be easy to excuse these shortcomings, and the cheeky The Right Stuff rip-offs. But it does, so it isn’t.
