I always hate it when one obnoxious, nasty, ridiculous screeching housemate gets put on a pedestal and overhyped as being the whole show, and gain fanbases who blindly excuse everything they do.
It's happened with a lot of series, Marc, Perez, Farrah. I was glad to see all of them go, and it speaks volumes that despite all their hype, none of them even made the final. Marc technically went as soon as people had the chance to evict him. Vote to save might have helped Perez and Farrah last longer, but when they were evicted they still went against all the other housemates. That to me shows how overrated those sort of housemates are, even in a vote to save they aren't all that popular despite all the screentime and hype. Clearly a lot of people didn't think they were the whole show.
Bear is the closest to that type of housemate this series, although he isn't quite as overhyped yet. As for Lewis, would he be any great loss really? There's the showmance with Marnie, and the series will always make sure we have a showmance shoved down our throats, but what else is he bringing really? If he goes in a vote to save, then what he's bringing obviously isn't appealing to enough viewers.
