Finished watching Redwater last night. Overall I thought it wasn't bad. The oirishy bits you have to become immune to, but I didn't really notice them after the first couple of episodes. Still a few "I doubt anyone has ever said that" bits of dialogue here and there, but I thought the acting was quite good. The plot wasn't bad, it looked good on screen.
I know that all sounds a bit 'faint praise', but it was very watchable (esp. from episode 3 on).
