Let's face it, Will Smith is a money making deal. Whether he's recording albums or coming out with a blockbuster movie, lines are always long and the product never fails to deliver. I Am Legend doesn't miss either.
Sound: Crisp and clean. I would have rather seen this released in 6.1 or 7.1 but of course, 5.1 doesn't fail to deliver. The TrueHD makes a great addition to screams, bangs and pings. Not to mention when Smith's character, Neville, falls on his knife. You can hear the blade going through material and meat.
Video: Clear, maybe a little too real. Warner Bros. pulled out all the stops on this. The packaging says 1080p or 1080i and they aren't lying. Compression is not too much of a worry in this film. It may be a little too close for comfort in some scenes.
Extras: The viral video (no not YouTube, an actual virus education) is actually quite interesting. It's similar to a biology class, just a little more fun and gives more basis for the movie. If you saw the animated comics leading up to the original theatrical release, you are in luck, all four are included in the special feature section.
SPOILER WARNING:
The alternate ending is definitely different. Granted, Will Smith might not have gotten the same acclaim if he lived. Regardless, giving the female infected to her "boyfriend" and bypassing the attack, Neville and his newly acquired, non-infected friends leave the city and send a new broadcast message letting people know they are not alone.
Overall Value: This movie provides a good bang for the buck. The video is very clear and the sound embedding is almost perfect. Hats off to Warner Bros.
