Honestly the game has pretty much ruined every character for me. I genuinely can't find any of them as charming as the original. Least of all the MC. The only thing he has going for him is that - as a midget - he can somehow roundhouse kick someone in the face. That's it, that's the only miracle he's capable of. He doesn't have an amazing dick, he doesn't have mind control powers, he isn't rich, he isn't a genuinely nice guy with the charisma to match... what's the hook for me to keep playing him? He's no longer the only guy on the island for that advantage to work either! There's nothing believable about this and despite me mentioning mind control powers at least it can suspend my disbelief. There's nothing I can use here to do that.
Plus you made him a simp in episodes of things that would have people go full no contact over. Elena being the most horrifying example. She ruins your life. Then she cries. Never mind she claims to be a family friend and thinks of you as a son. She cries and you forgive the crocodile. Never mind the anguish you felt over the fact your entire future is ruined. Sophia is whatever, she has no emotional ties to you at all. She can be a monster and you can tell her to fuck off forever. Elena, though? She's supposedly family and she pulls this. I don't even know what her motivation actually was other than that you wanted to make her the biggest bitch imaginable.
I don't even know if I have any suggestion to fix the characters. I mean, the only one I have is maybe for Elena in that she fears you leaving because of her own abandonment issues. She wants you to stay on the island and in a moment of a panic attack did the worst action she could to keep you. She's too prideful to admit it, etc, so you get the bullshit. Thing is, though, you gotta hint at that. You gotta let the player figure that out and even use that to his advantage.
Either way, though, they aren't the characters I loved. You decided to go for generic serious tones instead of just having fun with it. The outlandish shit in the original - I admittedly didn't like that MC much either, but he grew on me - was fun. It was silly, it got my dick hard, it didn't try to drag me into a pit of depression. You created what was a selfish young adult, but a young adult still. His motivations were believable. Now you got some jackass that thinks he's trophy husband material when he's lucky he can even reach someone's face with his foot. He is not David Spade, even David Spade is taller than him... and much more charming and knows how to dress.
All of this may sound harsh... but honestly it's the same kick in the groin I felt playing the Premium Edition. Equal reaction, my man.
