Spielberg. Post ROTLA he became so formulaic that it was nauseating. Followed closely by Lucas.
Actor, Bruce Willis. Luckiest dude that ever lived. I have never understood why him and his face wince ever became famous.
Agree about WIllis (everything except 'Die Hard' which is a classic and he was great in), but saying that Spielberg was formulaic in everything post 1981 is absurd. Films like 'E.T.' (which went against the grain and cast the alien as a good guy), 'The Color Purple', 'Empire of the Sun', 'Schindlers List', 'Jurassic Park', 'Amistad', 'Saving Private Ryan', 'Minority Report', 'Catch Me if you Can', 'Munich', The Adventures of Tintin', 'Lincoln', and 'Bridge of Spies' all prove that statement to be false.
