I started to watch this on Prime, based on the 6.9 IMDB score.
To be clear I only watched the 1st 10 minutes, to that point it was so awful I couldn't bear to watch any more. The first few seconds already revealed terrible acting, unconvincing action, amateurish camera work and awful dialogue.
At around 5 minutes in the the female lead has a wound to left of her mouth, in the previous scene it was on the right. That's what really done it for me { I went back and checked, there was no mirror shot or other explanation)..
I know that there are many films that polarise an audience, these are generally made with passion and/or enthusiasm, this isn't one of them. If you value your time this is one to avoid.
