By serendipity, we caught I AM LEGEND tonight and, like Steve, I thought it was going along pretty darned well... until the bad guys showed up and turned out to be a bunch of Hulk-roaring cartoons. (Makes it easier to adapt to a video game, I suppose.) Nevertheless, Smith puts a lot of heart into his performance and, despite running on a relatively flat tire for too much of its third act, it's got three or four terrific sequences definitely worth seeing.
