Depends on your definition of "bomb." I Am Legend, or as I call it, The Last Man On Erf set a opening weekend record and grossed respectably. However, I found the special effects terrible, the plot thin, and the prospect of Will Smith being a doctor specializing in virology utterly preposterous.
Okay, Will and the rest of you, we get it: “Blood Is Thicker Than Country.”
Probably a little more believable than Richard Pryor being a computer whiz in Superman III.
