I Am Legend is a pretty good movie. Although the zombies appear really stupid looking if you see them too long (The very first one he sees is wearing golf pants) they manage to startle you when they jump out of a dark doorway making guinea pig sounds. The plot is very good all except for the ending *spoiler alert* where he sacrifices his life to safe some people that most of the movie goers won't care about, other than that it's all good (but the dog dies.)
Some of the coolest special effects don't even occur when Will Smith is fighting freaks who want to eat his flesh, the very best effects are the way New York City was aged. The weeds poking through the cement, the cars stopped in their places, and the buildings covered in quarantine plastic.
When Will Smith isn't fighting it definitely isn't boring due to lack of dialogue, even though 80% of the movie only has Robert Neville and has dog, the directors have filled the plot with flashbacks and interesting things for Will to say to his dog, such as,"Eat your vegetables, I'm not kidding now."
Most of the zombie stuff is only mildly scary and the blood is kept to a minimum. The part with probably the most violence in the whole movie is when he sets a trap for them and starts mowing 'em over in his SUV.
In conclusion if you're looking for a good movie to go see, this would be a good one to see, unless you have really small children.
