Really nice quality in HD. Not just the technical aspect, but the set lighting and post-production colouring - equal in my view to any recent feature film. The 5.1 sound was a good bonus, too. Everything being equal, it should now make the show a really good 'sell' around the world.
The CGI shown so far was good - not brilliant, but I didn't have a huge problem with it, knowing their budget was constrained. I'd rather have reasonable visuals, with brilliant writing, acting and direction, than the other way around. Hopefully, if the show gets good overseas sales, then budget can be increased for future series'.
