I am big fan of Tarantino and Rodriguez's grindhouse films, and I will compare this film with those two. The look is grim and grindhouse and the violence evil and extreme.
The running time on 73 minutes is perfect, as all bulls**t and fill is cut.
The reason it doesn't get a 10 is that it feels a liiitle slow for a about ten minutes after 45 minutes, but it compensates with a blast of an ending.
To be honest I didn't expect much, but it was 73 minutes of lots of fun, bloody violence and sexy action.
