Personally, I can ignore substandard special effects and CGI, if the story and acting are strong enough to carry the movie through to the end. Will Smith does an excellent job of portraying a man so lonely, teetering on the edge of insanity and just plain giving up, yet still so driven to find a cure and help the afflicted, who at the same time he fears so much. This movie was excellent when I saw it in the theatre...right up to the ending, which I just did not buy in to. I won't spoil it for you, but I will say this...BUY THE 2 DISC VERSION WITH THE ALTERNATE ENDING. It's sooooo much better, and fits the story very well, it has meaning, it's almost touching.. I don't know how the studio decided to go with the theatrical ending over this one, but given Hollywood is stuck in an age of endless sequels, I suppose we should be thankful for the almost perfect film we were given. The extras on this set are good, but I would love to hear some in depth running commentary from Will Smith on this role. He's grown into such an accomplished actor, and this film proves he can carry a good story and take the audience with him on a suspenseful ride! 4 out of 5 stars!
