I didn't like the first episode but I'm loving Peter Capaldi now, I think he's really bedded into the role. I hated the Robin Hood episode though :(
It could be a bit more frightening but I think they're stuck with a lot of people perceiving it s a kid's programme which it originally was but it has actually moved more towards an adults programme but the production seems to be stuck midway in a state of flux. Jump towards a more adult market and you'll have something really worthwhile I think, stay in this quasi children's show format and you risk losing something which could be really excellent.
