I had purchased this as a DVD in Asia years ago.
I liked it enough to buy it again as a Blu-ray, so that tells you a lot about the movie right there.
Funny thing was (for me), that the dialog is somewhat different all throughout the movie, noticeably if you have watched another edit of the film about 6 times. There is a good chance this will apply to precisely no other people buying this movie, and really it did not detract from the film at all, nor does it change the plot/ending, just made it an odd thing for me to watch, i wanted to get another TV with the DVD hooked up and compare them side by side.....
It is a good film with a really superb cast, it action packed and guns and kick'in ass... and she's very hot... and it's cheap, so worst case if you hate it, give it to your enemy!
