Alison and Helena unnecessary filler?
I really liked the Alison and Helena characters in season 1. The duality of Sarah vs Helena was gripping and powerful.
I also really liked the stark contrast of Alison and her trying to figure out who her monitor was.
However the characters became extremely pointless by around season 2 or 3.
Helena just seemed to get kidnapped by someone different every few episodes, and didn't really seem to contribute anything to overall plot. And Alison went from being an ordinary and naive soccer mum to figuring out her husband was a monitor, and torturing him for answers, to trying to run for some sort of local election and doing theatre.
Additionally the whole Breaking Bad element of Alison's scenes seemed like a pathetic way of trying to get fans of BB to watch the show. It really had nothing to do with anything, and they even reference how similar their situation is the Breaking Bad at one point.
The whole story arc of their characters really just seems to go nowhere. You can pretty much delete all their scenes and you don't actually miss out on anything relevant to the main story. So they effectively became filler characters?
I actually found myself groaning every time a scene with Donnie and Alison cooking up drugs or trying to act like gangstas started waiting for the scene to end so we can get back to the story.
I've never been a fan of filler in shows, but considering Orphan Black seasons are only 10 episodes long, there really doesn't seem to be any need for filler, other than just keeping the characters around for the sake of it.
Koalas are telepathic. Plus, they control the weather.
