Honestly,
What's with all the bad reviews?
This movie is like a comic brought to life; properly.
No, it doesn't have a $250 Mil budget; nor is it an Oscar winner.
But man, does it entertain. Lizzy Caplan is awesomely sexy, as a take-no-prisoners gun-slinging widow, enduring being victimized and targeted by a lunatic father in law, his murderous friend and his insane nephew, a whole bunch of very barbaric men and at least one bloodthirsty voodoo witch... all while trying to keep a promise to her deceased husband. Seriously, I was very pleasantly surprised how satisfying this movie was.
Ignore the haters. Just go watch it.
