Indeed. It's worth it for the scenery alone.
I hope Arthur comes back. I've found he and Lisa to be the most entertaining characters, and I quite like Cerys as well. I hope Arthur maintains his "apparently dodgy and unreliable, but kind and humorous, and actually more to him than meets the eye" character. Some of us had some fanciful theories about him at one point (mine perhaps more fanciful than anyone's) that he might be, e.g. an undercover cop investigating corrupt other cops.
However, it does rather seem that he was what he appeared - a vulnerable (to use Faith's word) person who was manipulated into doing dirty business, but whose basic decency finally triumphed.
I don't quite see how either Evan or Steve are going to survive in one piece, once Gayle Reardon's family start looking for them.
I wonder how many of the police will remain in their jobs? I hope at least that Terry makes sergeant, although I don't think "Susan" will be recommending him for promotion.
