Alf and Irene really needs more storylines. They are becoming "boring" sadly but I did enjoy his ANZAC storyline. I hope he will get more storylines soon. He hasn't had much to do since 2005 sadly.
BadRomance and SarahCadhill, I concur with your statements but I think Kate Ritchie will come back one day. She is missed by many fans and she is still a massively popular character. But I don't think we will see Sally again for the foreseeable future. Maybe in 3 years time? I miss Alf's scenes with Sally - their relationship was very special in the Bay and I will never forget her poignant line to Alf. "You will always be Mr Stewart to me, Alf". Their second farewell in 2013 was very moving too. I was really hoping that we could find out if Pippa Jr is ok after her treatments in the USA. Ray Meagher, Ada Nicodemou, Lynne McGranger and Emily Symons have always said that Kate's exit has left a massive void and they keep wanting her to come back.
Marilyn is my favourite current character and I'm going to miss her when Emily Symons is on maternity leave. Her return is a massive success and many fans love the character of Marilyn. She's a ditzy woman but she has a good heart. I didn't like the Marilyn/Nicole baby storyline in 2011 but I think many fans want to forget that it happened (I don't blame them).
Home and Away needs more long-term characters and we only have Alf, Irene, Marilyn and Leah. I'm fed up of the younger actors using Home and Away as a training ground/stepping ground is insulting for the likes of Ray Meagher, Kate Richie, Georgie Parker, etc. I really hope Roo isn't leaving anytime soon but Georgie Parker is an exceptional actress so she may want to move on to do other things.
I'm bored of the endless love triangles and teen dramas. It's not for me but I know everyone has different opinions. I don't like any of the characters introduced in 2013 apart from Ricky. Bonnie Sveen is excellent and I can invest in Ricky.
