Two-Face (Tommy Lee Jones) – Batman Forever
Tommy Lee Jones should have been a terrific piece of casting for Harvey Dent but sadly he tried to out-comedy Jim Carrey and just embarrassed himself in the process.
Talia Al Ghul – The Dark Knight Rises
Not only is Talia Al-Ghul an afterthought, a waste of a talented actress and great character, she also retroactively ruins Bane’s character. Plus, she has a hilariously bad death scene.
Lex Luthor – Batman v Superman: Dawn of Justice

Ding ding ding! Reimagining Lex Luthor as a precocious but insane rich kid could have worked, but Jesse Eisenberg is just too Riddler to be a believable Lex Luthor.
