"i am legend"

I just saw this at the Palisades IMAX, fresh out from release. a typical hero movie ... i'd rate it as "okay" (spoiler below).

The good: imaginative - cure for cancer turned disaster.
The bad: camera work - close up with a lot of motion, yes they intend to make us nervous, but it's way over done and i'm dizzy.
The ugly: cliche has it for a solo hero, wounded, made great discovery and died for the cause. guns, medicine, ghosts. the best friend (dog) of the hero dies. An angle comes to the rescue because she believes in god (! GWB's propaganda?)

Will Smith did a decent job, but how much can you act as almost the sole actor in a whole two hours?
