I've pretty much the same ranking as you, I remember in the 1st HL show calling Bastien "Fourbastien" lol, I judged him right at the very first sight! I really hate him. And yeah, I was a bit tired of Fanny lately, but I was sad she was evicted this way. A bit unfair. Production clearly wanted her out. (it was either her or Bastien this week).
I don't like this season because it misses something, there is no more magic as the previous season. This season reminds me SS8, entertaining sometimes and good storylines maybe but lack of magic. And... these contestants are too much fanatics of SS and of the contestants from the previous Secret Story seasons. Also I have a new view at the contestants since I used to talk to some other contestants from other seasons and other reality shows, I see them too "malade mentale" now kkkkk. They all have their place in an asilyum I think kkk.
Marvin to me wasn't a big character. Except to yell, I didn't like too much his personality, it's not what SS teached us to be used to, but I agree with per example last season (and yet, we had lots of big characters last season: emilie, rémi, coralie, jonathan, nicolas, mélanie, ali, alia, karisma, lolo) or ss8, this season had more big characters, we saw more of them. Mélanie alone against everyone, then liked, then she betrays, and isolates with Bastien, Sarah hated by everyone in the house and in the outside, then likeable, and liked by many, Julien..., Thomas and his secret missions and his "ta gueule", Fanny and her funny expressions + her baby and... even Anaïs played a part in this season.
