I agree with those who think show went downhill after 2nd series. I also agree the Claire character got to be increasingly tiresome - forever poking her nose in matters, in her 'preachy' tone. The Roger character never struck a chord with me. The pairing of Roger and Brianna just didn't work and seemed poor casting, in my opinion. This show is a good example of writers and producers padding out a story over too many series. Could have been done in 3 series, not 5. In a nutshell, it ran out of steam and just chugged on too long.
