bringing back characters isnt something that happens alot in soaps, but when it does it makes a good storyline because it shows us that characters live on even after theyve left, it makes it more real. it has a good impact on bringing back characters on the public as well, because if they liked the character and it left but came back they would watch it.
like peggy returning today on EE, that was great, because its something different to keep us hooked and it lets us know how the character is doing. if you bring them back for a couple of episodes, i think that works better, because any more then you will get bored of the character. i believe they did it with spider in corri, it was nice to see how he was doing for just a couple of episodes and then he left again, peggy is fantastic, only with certain characters you can do it though, peggy will return full tiem i know, but tonight she was like a breathe of fresh air for the soap. lisa was another who tehy did it, she had a good storyline, she came back for her baby got revenge then left. it was good to see her back againa s well and she was like a breathe of fresh air as well, but if she had stayed any longer we would have gotten tired of her.
so i am a fan of bringing back long missed characters, like the mitchels especially paggy.
