I'm from Belgium, so I know Matthias Schoonaerts is a very good actor. However, in this series his acting limits itself to raising his head very slowly while desperately trying to look like a bad ass and making short grunts and growls which I hope weren't in the script.
I'm focussing at Schoonaerts because he played Django, but the other characters in this series perform on the same level. They can do better. I know they can. I recognise most of them from other programs where they did a fine job!
It's not just the acting though. The whole cinematography is a bit off. The footage is either too dark or even a bit too shakey. At first I didn't know what it was I didn't like about it. It's that subtle.
And last but not least: the story. It's just not strong enough to play in the same league as the Django westerns the producers are aiming for.
Pity.
