sorry jav but not all villains can be wordless badasses like darth maul
the point isnt that all villains should be one dimensional dark, brooding, or menacing. its that ren is a poorly done character and unlikable. which i mean, i guess is a good trait for a villain, but he's not even likable as a villain. he's not a good villain, he's pretty incompetent. his tantrums would be fine and great and intimidating, except other aspects of his character detracts from them, and makes them comedic rather than menacing. he isnt very good at his job as a villain.
also, if their goal was to set him up to be likeable and sympathetic in order to give him a heel face turn, thats being poorly done as well, because he's not even likeable in that sense. i want him to lose, i dont want him to have an success, and i hope he ends poorly, because he is entirely unlikable a character and his motivation is half assed, his struggle is poorly portrayed and lacking in logic, and he has pretty much already committed acts that are beyond the point of a redemption arc. he's just not a very sympathetic character, i cant relate, and he's unlikable.
not to mention the stuff i listed earlier in my previous post about how his character and back story dont even make sense.
