"August Underground's Penance" is basically the personal home video of two sociopathic killers on murder spree.Again two nameless butchers played by Fred Vogel and Cristie Whiles videotape their bloodthirsty madness,but "Penance" shows also their slow decline.First of all I'm not a big fan of "August Underground" series.Still as a lover of extreme cinema who had previously seen "August Underground" and "August Underground's Mordum" I really wanted to see the final installment.This time the faux-VHS look of Mordum has been tossed aside in favor of a more contemporary digital look.The gore effects made by ToeTag crew are very convincing and the violence is dirty and vile.There are some boring moments,but overall "Penance" is not as perverted and repulsive as "Mordum".7 out of 10.
