Have you seen the original DON ? It was an Amitabh film all the way ? The replica DON was a gadget and gizmo gimmickry show all the way. You are a SRK fan so you liked the movie but it was wanst liked by many and hence it was only an average success inspite of some real innovative marketing. SRK needs to watch out as hes yet to give real solo hit since 2004 while his competitors like Amir and Hritik are giving super hits once after the other.
SO far as doing a DDLJ or KKHH is concerned , have you heard of Khuddaar,Amar Akbar Anthony, Naseeb, Satte pe Satta , Mr Natwarlal , Suhaag, Hera Pheri which bring out the lighter side of the Big B ? So far as Darr is concerned , have you seen Parvana because you will see the difference between a class act from a raw amitabh and a mediocre one from a raw SRK ?
