Good at First - Ending that Stinks!

Rating: 7/10 (18 December 2007)

First of all, I haven't read the book. After seeing the movie, I figured it would have to have been based off of one and discovered that, yes, it's based off of Richard Matheson's novel, I Am Legend -- which I will definitely be buying.
Just like Tom Cruise's War of the Worlds left a lot to be desired - not explaining things - this movie does the same. In WoW - it was like they depended on Cruise's star status instead of plot - and this one did too. They started off GREAT - and gave a lot of anticipation but instead of getting satisfaction as they progressed, you're left with a million questions and a desire for something more.
Let me start off by saying that as a whole, I liked the movie, and much of what I didn't like about it could have been fixed if it were longer than 101 minutes - they could have added a lot more details.
Will Smith's character is supposed to be a highly intelligent man but in one scene where his mannequin, "Fred" appears in a different place from where Smith had placed him, instead of wondering how "Fred" got there, Smith instead screams at him and appears to have a nervous breakdown. If I were "alone" in a place with unthinking, unfeeling monsters lurking in the dark places, I think I'd be wondering how "Fred" got moved. Also, in an earlier scene, the leader of the mutants walks into the sunlight, burning his face and Smith's character comments that the behavior is unlike human behavior. However, the mutants set a trap for Smith that is exactly like the trap he sets for one of them. OK? That isn't like intelligent human behavior? They're obviously thinking and planning schemes.
One other thing that confused me -- when Smith enters his basement lab for the first time, we notice that he is bathed in black light - UV light. However, when Smith, the woman and the boy retreat to the lab to escape the mutants, he doesn't turn on the lights. Also along this same train of thought - why didn't he reinforce his roof? He lives in a brick house and he's put steel shutters on his windows, but the roof he leaves as wood and shingles.
And, at the very end of the movie, the lady gives the blood containing the cure to the people at the survivor colony. Why are we supposed to believe that they would have the resources or the knowledge to do something with that blood? The one person who could have developed it into something to administer to the mutants is gone.
