A good plot twist to me is when you’re kept on your feet and you keep guessing who’s the bad guy, not one where a character is made to be unnecessarily creepy and then we find out he’s not the bad guy. Like why? It’s like the character was formed just to be the guy everyone suspects. The character has no character arc, there’s no back story and no explanation why the character acts suspiciously. It’s just like the character has made it his life goal to be suspicious for no good reason.
