Can Someone Explain the Problem To Me?

I was catching up on my blog reading, and of course Laurell K. Hamilton's blog is a must-read for me.  She's been enjoying movies this summer (just like the Goldbugs), and we've seen most of the same movies Hamilton and her family has seen.

She talked about Dark Knight, her latest in the summer viewing series, and she ranked them.  Hancock (a Goldbugs favorite) was ranked pretty high, but she mentions that there was flaw in it.  Here's what she said:

Oh, and the fact that I put Hancock ahead of both The Hulk and Dark Knight . . . Hancock was a flawed movie, I won’t argue that, but the story line was ambitious, and after days of thinking about it, I can’t figure out how to fix the big twist in the movie, without giving it all away. If I can’t figure out to do it better, I try not to bitch. Also, Will Smith can carry a movie on his back, up a hill in a snow storm; and make you applaud the whole way.

It sounds like she thinks there's a problem with the plot twist.  (I'm not going to talk about the twist here, but be warned that spoilers might show up in the comments.)  I don't see the flaw.  I don't see what needs to be fixed.  I'm not arguing; there very well might be a problem.  I just want someone to explain what it is.

Please weigh in!

I'm with you; I didn't have/find a problem with the plot twist, either. *curious*

Hm, reading some of the "splat" reviews on Rotten Tomatoes might answer your question.
