The Phelan/Vinny con storyline is turning out to be a very good one, despite major artistic licence being used for the planning application (or one could call it lack of research depending on how kindly one's feeling towards the Corrie team :D).
Moral chameleon Todd being tempted by the serpent Phelan adds another layer of complexity. Will Todd succumb and, if so, how far will he be willing to go to see his friends and neighbours ripped off?
I used to think the actors who play Beth and Craig were OK but I've recently changed my opinion I'm afraid. I think they're probably better as amusing background characters rather than carrying serious storylines at the forefront of the show. Mind you, they're not the only ones to whom that applies by any means.
