I disagree w.rajinikanth has being overrated as an "actor", unlike srk who is not only overrated as an actor but also has an entertainer.
Rajinikanth has done villian,comedy,romance,drama, and for the past decade action roles. Yes its true, tht in sivaji his stunts wer way over board and he needs to stop doing those stunt and style stuff since its the usual.
He's been doin it 4 a decade, only thin instd of cigarette popping(which ws cool back in the days)now its gum, some other kiddy stuff.
In srk's case he has tried to do roles tht ar diff. from his usual romantic stuff but faild misrably as a villain in the past and in don. As far as his humor is concrned, he will be the first,last, and only person to laugh at his jokes. Srk too does not hav style just the self propsd king status w/his media boyfriends.
Rajniknth has nevr used media and hs never prmotd his movie, endorsemnts, still his images ar used for free on many accecories ranging from school items to being pasted on the face of sai baba and other gods to be worshipd by his fans.
In some ways rajini fans ar treating him literally like gods, but he does not respond and build temples placing his statue besides the gods in temples.
