I am Legend with the prince of Bel Air. The last 20 minutes are a total shit fest of a rewritten ending (it is pretty well documented and plain evidence considering what's still in the film) that totally betrays and inverts the meaning of the original story while injecting a really cringeworthy religious component to the matter (I generally don't mind, but it's just so bad and by the numbers...). Nonetheless, even if the film had its original, more faithful conclusion, it wouldn't have been anything else than a mediocre take on the story, dressed into the usual modern Hollywood bombast : The film has to open up with an action sequence full of already outdated CGIs (pretty jarring when you're 4 minutes in) and Neville can't just be the last man on earth or a military doctor, he has to be the uber-scientist man of the year with a state of the art lab in the basement. His family can't just be dead, it has to be all dramatic and shown on screen. I dunno, is that supposed to make the character more interesting for Will Smith "grand" (OK, but nothing special) performance ?
Also, have Emma Thompson just for the pre-credit bits ? Get out of here.
Weakest movie version by far (The Omega Man is pretty wack but the intro is good and Heston has phenomenal presence, as usual). Stick with the Vincent Price's Last Man of Earth. It was on archive.org back then since no one has the rights for that. Still pretty chilling.
