I saw the bad reviews, and as I had nothing better to do, I watched this anyway.
Yes, there's a problem with the sound. Too much muffling and background noise to understand what's been said. But, this isn't a film that requires every word to be heard to make sense.
But the acting was good. The story was good. And I would watch this again.
I'd have given it a 7 if the sound was of a good quality.
