At first, I liked the series for nice sceneries, interesting characters and promising troubles they try to confront.

But then "baddies" became more and more demonized and smart protagonist just starts doing stupid things one after other and reacting on all enemy lunges with "well what could we do". Poldark is presented to us as too nice and equitable guy to do bad to antagonist while he does quite immoral things to beloved. And it doesn't make him a complex character but the illogical and hypocrite one. The antagonists aren't any deep at all — they just do bad things and have no background. Most of this things feel like a lazy scripting.

The idea of series is quite primitive: good guys dramatically struggle until the bad guys are randomly defeated in the end without their participation.
