I am a very big fan of shah rukh khan and had watch many of his movies but have find few of his movies so worst that I don’t want to watch them again they are:
1 . KABHI KHUSHI KABHI GHAM ( the movie was good until the enterance of kareena kapoor )
2 . duplicate ( over acting by shahrukh khan )
3 . badshah ( again over acting )
4 . chalte chalte ( acting was good but story was closely like hum timhare hain sanam )
5 . maya maim sahab
6 . OH DARLING YEH HAI INDIA ( OVER ACTING AGAIN )
7 . PHIR BHI DIL HAI HINDUTANI ( NOT GOOD DIRECTION )
8 . DIL SE ( GREAT MUSIC BUT WORST FILM )
9 . 1 2 KA 4 ( GREAT MUSIC AGAIN AND WORST FILM )
10 . CHAMATKAR ( VERY LOOSE PLOT )
On the other hand all of his movies are great or ok but believe me I am his big fan.
