Not enough substance, but it was still very entertaining.

Rating: 7/10 (14 December 2007)

"I Am Legend" runs at about 90 minutes without credits, and with very little background information or talking from Will Smith, we have no reason to support Will Smith on his conquest to survive.
Will Smith plays Roger Neville, a scientist who tried to develop a cure for cancer, and ended up turning the people into vampire like creatures. He now is what appears to be the last living man on Earth, and he and his dog Sam try to keep on living life. Will Smith gave a good performance, but the character is so one dimensional. For most of the movie he seems very angry and serious, and then he has the occasional joke, that usually caused a light chuckle in the audience. He was still somehow likable, but he could've been a much better character, considering this whole movie is practically a one man show for him. Any other characters in the story don't have enough screen time for the audience to care about them, and they are very underdeveloped (even more so than him).
A lot of action-horror movies are missing heart, and that's a big positive for this one. It has a heart, and it has some touching moments. This layered the movie and made it more than just a bunch of special effects and jump scenes right after each other.
In the end, this was a good movie, but I preferred the Omega Man over this.
My rating: *** out of ****. 90 mins. PG-13 for violence.
