Hats of to the BBC for this, I've just watched episode 1 and LOVE IT! This brand new series has the right sort of production value quality to do the concept justice, and does not in anyway seem as cheap as the previous series from the last century.
Sound: excellent! Visuals: excellent! Lighting: excellent! Acting: Excellent! Characters: Excellent (and creepy!!) Dialogue: Excellent! Timing: Excellent! All the other categories that I cannot think of: Excellent!
I'm so glad that the BBC has come up with something that beats the US made high production value dramas like Battlestar or Flash Forward.
I will put 5 stars against this series just as soon as I can work out how to do it on IMDb!
