It's day 1, so these are still first impressions, and opinions are highly liable to change, but after one episode, I like:
Andy - He's probably the most sensible one. I like that he's already trying to talk sense into the other HMs, which will likely prove valuable this series.
Lateysha - Purely for the stupidly exaggerated drama she is already bringing. She seems quite stupid though, so she could become annoying.
Andrew - I like that he's perceptive, willing to play the game and doesn't really take any BS. He talks himself up a lot and he's probably a sociopath, so I might end up hating him, but he seems likeable so far.
Evelyn - Not as obnoxious in the house as she was in her VT. Plus she's ONE OF US, so I feel like I should support her for now.
Hughie - I got a good vibe from him. He seems fairly down to earth, and from what I can see, he's one of the few "normies" this series.
Jackson - He seems weird, but I like weird. Already starting up a homoerotic bromance with Sam, whilst pining after Georgina. Could end up a mess.
I can't stand:
Charlie - She admits that she treated Jason like shit in their relationship, and that she didn't realize she had something good with him until it was too late, yet is milking all this undeserved sympathy for it. The worst part is that her fellow "others" are indulging her in this. I won't have none of Ryan's "don't speak down about a girl" BS. If she's a nightmare girlfriend who takes freely, without giving anything back, as Charlie proudly admits to being, then she certainly doesn't deserve praise.
Ryan - UGH. Just UGH. He's like a gobbier, vainer and stupider Mark from Power trip. It does not surprise me to learn that he used to run in the same social circles as Mark.
Marco - How did Marco Pierre White raise THIS?
The rest of them seem fairly innocuous so far, but my list will undoubtedly change a lot in the coming days. First impressions aren't always correct.
