1. Izzy and Karl's affair/Izzy in general - i hated this storyline. My love and respect for Karl nosedived and he's never really been forgiven in my eyes, i still think Susan can do better. I hated the way Susan was treated while this was going on. Lifelong friends like Harold and Lou took the side of the nasty newcomer because she flashed a smile and a bit of cleavage and treated Susan like a jealous, petty woman intimidated by a younger rival. Even when Izzy's nasty streak was exposed Harold and Lou still defended her as if she was their friend, even when she happily screwed up the lives of their actual friends/family. I lost a lot of the warmth that Neighbours provided and its never been able to recapture that magic.
2. Steph's two exits - i hated Steph so i dread to think what her fans thought of her exits. I was expecting them to be high profile and dramatic after ten years on the show (which admittedly they were) but she left under such a cloud both times it was really unsatisfying even for viewers who didn't like her. Accidently killing Ringo and going to prison was a bit of a slap in the face but her return and stealing a baby and being sectioned was just as bad. They could at least have rectifyed their first mistake on her second stint and had her reunited with her children and then leave.
3. The Parkers mk2 - not counting Stuart or Ned as i actually really liked them but the dreadful Miranda, Steve, Bridget and Riley (although him slightly less as he wasn't there long enough to be that annoying). This was during their 'back to basics' revamp which meant introducing a very bland family and painiting everything in sight grey! The family were annoying (not so much Steve but Miranda was quite snooty and hard to warm to and Bridget was just whiney). Miranda's treatment of Susan after the accident with Bridget really confounded my hatred of her and i cared so little about Bridget i wasn't bothered what happened to her. The only interesting member of the family was Miranda's sister Nicola and they wrote her out abruptly 9probably for being a bit too interesting!).
4. AndrewNatasha/Summer - these three dominated everything for a time. There was no escaping them. Andrew's business ideas, Summer's journalism portfolio, Natasha just being a general nuisance featured in almost every episode for months. Plus i never quite believed after all the build up to Summer/Andrew and her staying in Ramsay Street to be with him she'd be so ok with breaking up with him and him living happily ever after with Tash.
5. Recasting Brad - i thought out of all the recasts i'd hate Lauren's more as i remember the original Lauren and really liked her but Brad's is more annoying. Not only is it Scott Hunter from Home and Away but the character has morphed into an extension of Scott Hunter from Home and Away. Basically he is bland and annoying and always on his high horse. Nothing like the original character, in fact the original character would have found this Brad annoying as well.
6. Stonie and Annalise's affair - Sam and Annalise were perfect together, so why they threw in this tacky affair just to write Annalise out under a cloud was very annoying and shouldn't have happened. I'm kind of pacified that Sam and Annalise reunited off screen and are still going strong but it was just a rubbish way to write such an iconic character out.
7. Hannah Martin's friend Teabag - seriously Teabag? Hannah was annoying on her own without giving her stupid friends stupid names.
8. Stingray and Sky - after ruining the perfectly good Sky/Boyd to make way for Sky/Dylan i'd finally accepted she probably loved him only to split them up and have her sleep with Stingray and produce a boring 'who's the daddy' storyline. When it resulted in Stingray and Sky getting together i was bored to tears and never really believed they were in love with each other. When he died her grief was hard to take seriously and i kept thinking Stingray in death had finally been reunited with his true love (Serena).
9. Harold erasing his first wife in favour of Madge - Harold had kids, a home and life with this woman yet we constantly get the 'Madge is the love of my life' spiel while glossing over his life with his first wife who he must have loved at some point. Alf Stewart in Home and Away is the same. Because we never met these wives (only their kids who also rarely mention themits as if they neverexisted (which technically they didn't but even so).
10. Cameron/Robert - the storyline was really good but the whole they are so identical that the third triplet, mother and father can't tell them apart was a bit too much. Plus it'd be quite nice to know how Robert's getting on these days.
