Despite recent underperformers he is still the one calling the shots right. Except the smaller films in 2011, he really hasn't had any film clashing or even release a week later against his film. One yes it was box office & two, none in the industry wanted to deny what he demanded. Reshma & gang weren't looking after the distributors. That dominance within the industry has been there for decades & not just since 2010. Even last decade, no matter how many films failed, Salman Khan still remained powerful in the industry. Except the Srk right, none got in his way.
So when I say dominance, that has never relied upon the box office success. Even Salman knows it. The other two Khans never had anything like that.
Dabangg 3 isn't a rushed product. Radhe has just started filming so can't call it a rushed product. Because that script was being worked upon along with Bharat. If you look at it even Inshallah script wasn't entirely ready.
Regarding Korean remakes, all depends on how well they desify them. Bharat was the most desified version but they just forgot masses won't buy a big star film with no conflict, emotional or physical being resolved. Bharat climax was among the most emotional ones Salman had ever done, just couldn't have the masses relate to that. Subtleness won't work. Nobody questioned Salman's performance. The only times Salman Khan has been questioned for his performance by public this entire decade is Veer (not many watched it), Tubelight (again not many watched but whoever watched didn't want to watch Salman like that) & Race 3 (that usual Saif was better). Salman the actor beyond the usual "Khan" impact hasn't really lost the trust among his audience. It's just that having used to see him dominate with outside Khans not getting that big numbers has changed in last 2 years. And this year toh everyone have scored big - right from Hrithik, Shahid to Akki, Ajay, Ayushmann... There used to be clear difference in what Salman / Aamir used to score compared to the rest. So the media attention has turned a bit. Plus the Khans have not been in the news for their films like they used to be 2 years ago. As simple as that.
If there was no Padmaavat or Simmba last year then the numbers TOH did wouldn't have hurt Aamir that much. This is the first time Aamir went on the silent mode due to a film. Even Mela didn't entirely manage to do that. Thankfully he didn't follow Srk's silent mode.
