1. The director of Constantine and Britney Spears Greatest Hits.
2. The screenwriter of Poseidon (whose next project will be Marvel Comics' Thor).
3. More a remake of The Omega Man than a straight adaptation of the original story.

Why it might not suck:

1. Will Smith appears to be acting, not simply mugging for the camera.
2. Cinematography by the Director of Photography from the Lord of the Rings movies.
3. Decent trailer.
