What are some tamil movies where u think a character shouldve been played by someone else? whether thats because you think they made the movie flop or if someone silmply couldve made the film better?

i dont think the movie flopped because of her, but for me it was sri divya in Bangalore Naatkal, not that she was bad, just didnt suit the role imo. i could be biased and comparing her to narziya, personally she was one of my favorites in the OG bangalour days, but i sri divya suited the role regardless. i think someone like Keerthy Suresh or hell even narziya herself couldve made a come back, but thats just imo. i also have seen people say that bobby simha was also a bad casting, which i somewhat agree with.
