Well actually it is adapted from a play from Shakespeare, but it's not your typical Shakespearian adaptation you'll get here. Although the dialog seems to be spoken as it stood in the book (I don't know it word for word, but they use Shakespearian "language"), the whole thing is brought into a more modern world. It's not the first movie to do so, but I guess it's the first to be quite so brutal about it (literally speaking in this case).
The acting is quite good and with a bit of settling in time, you'll not even notice that this is done after a Shakespeare play, but see it as an action-drama (movie). And if you can do that, than you can enjoy it too (as much as it is possible for you).
