Not something I'd watch more than once.
There are better action movies out there if you just want to see fighting...and it had very little in the way of a plot...and if you are really *that* into Angelina Jolie, your 2 hours would be better spent on the internet looking for pictures, that will provide with much more satisfaction in that direction than the movie will.
Definately not worth buying....but you might as well rent it and watch it once, it's okay.
