Aiyaary is the latest big film on SGS. There is nothing since then except Bioscopewala and Love Sonia, as I have said a number of times. Stree and Badhaai Ho have not been shown on SGS.
On the other hand, in 2017, SGS premiered every single film (even low-grade ones like A Gentleman) along with Star Gold.
What makes you think so? Rather, Star Gold should rebrand now. On Tuesday, it will be 8 years since the last rebrand.
