There are many ways you could try to look at In the Blood. It's a stalwart reminder of traditional punch-and-kick action flicks standing firm for a tradition of non-CGI stunts. It's a throwback to the 1980s cheap thrills low-budget actioner but with an awesome woman delivering the body blows rather than over-muscled meatheads. It's unpretentious and uncomplicated.
It's also terrible. Which doesn't disqualify any of the above. Most of the stuff that comes to mind that fits those descriptions isn't very good either. Limited theatrical runs and video-on-demand is the new direct-to-VHS/DVD. Apparently there's still a racket for this kind of thing.
