1) Guddu - Wonder what SRK was thinking when he signed this film. Again a love story that began in college and then takes on a different direction.
2) Ram Jaane - Bad script, bad direction and bad acting. SRK tried too much to fit into the role and somewhere ended up screaming and mouthing bad language and completely lost it in this film.
3) Oh Darling Yeh Hai India - I guess SRK signed this film back then because of the name of the director of the film - Ketan Mehta. But alas, he did not know that Ketan would mess up royally and the end product would be a load of crap!
4) Josh - Again a well known director- Mansoor khan. What with QSQT and JJWS in his kitty. The film was supposed to be the Bollywood version of the well known play "The West Side Story". I guess, it was too much for the public to digest a loser like Chandrachur being paired opposite Aishwarya and SRK opposite a relatively unknown face. The screenplay of this film was poor and the film just lacked the punch.
5) Koyla - This has got to be one of Rakesh Roshan’s worst films. SRK’s make up was bad, story and screenplay have been rehashed a million times before in other films, just a bad bad film! Neither Madhuri nor SRK could save this film.
If I could add more to the list - as addendum.Here are the next five movies that SRK should really have not taken on.
6) English Babu Desi Mem
7) Zamaana Deewana
8) Trimurti
9) King Uncle
10) Yeh Lamhe Judaai Ke(I don’t think SRK even dubbed for the entire film.dialogues sounded like someone else’s voice).
