in fairness BB19 looked like a really good cast and they FLOPPED. Reverse can be said for BB17. There's a lot of people who i have no impression of for now, but I'm willing to overlook a 5 minute interview to give them a shot.
anyway here were my first impressions based off Ross Matthews harrowingly awkward interviews:
Chris - “My name is Swaggy C” NEXT
JC – I get seriously cracked vibes from him and idk if it's good cracked or bad cracked
Rachel – She seems sweet idk
Kaitlyn – She's so zen and seemingly has no self awareness. She seems fun but DEFINITELY going pre-jury.
Winston – He has such a nice smile

writing love notes to his dog

Steve – I can't see him lasting and I have no impression of him so eh
Scottie – I can't quite put my finger on him, he's so weird and his voice is sooo cartoonish
Angie – Always answering with “yas” instead of yes <3 I feared she'd be a cam-***** but she' actually very charismatic and unique
Kaycee – I really like her! She's very cool.
Brett – He really irks me idk why.
Sam – She's suuuuuper cute

Haleigh – She's ok no real impression
Faysal – idk why but I get Devin vibes from him
Angela – No impression tbh
Bayleigh – Won't make it far
Highlights are Kaitlyn, Sam and Angie, who must become an alliance tbh.
