Go See "Death Sentence" RIGHT EFFIN' NOW.
This movie gets back to what a "revenge movie" SHOULD be. It's not filled with a huge puddle of angst or the protagonist spending a lot of time on wishy-washy moralizing over what he should or shouldn't do. Yes, there's some buildup of "oh shit what have I gotten myself into", but when the gloves come off, oh my god. We're suddenly back to the days of Coffy, Foxy Brown, Death Wish, and Sudden Impact.
And it's a good thing, too. I am so goddamn sick of "action movies" that are PG-13. I grew up in the 80's where, by god, an action movie had a double-digit body count, excessive amounts of special effects wound prosthesis (everyone remember the tool shed scene in Commando?), and there were, in fact, sometimes nude women in the movie for no particular reason except that the sort of people who watched these movies also tended to like nude women.
These movies were rated R, and it was a great time to be alive.
This movie might not be able to cover all those bases, but damnit, it comes close. Do yourself a favor and indulge in what it has to offer you.
