Question Author
I agree with most of your general comments, folks. The writers are getting lazy. Too many clichés, too many (mostly dodgy) new characters introduced as somebody's love-child, too much emerging from doorways to see partner cheating etc, dragged-out storylines. Will Robert get caught out? No, it's yet another near miss.
I also think some of the characters' personalities have changed. The selfish Peter Barlow showed ridiculous concern and devotion to the tiresome Carla a few months ago, and the unfortunate Gary has become a bad guy whereas he had a bit of a conscience before.
