It's not about doing great business compared to the previous highest grossers but the current market potential wise as well. 3 Idiots doing 200cr a year after and so many movies doing over 100cr from 2010 onwards itself showed that the market potential is increasing every year, what Ghajini did in 2008 was definitely great then but certainly it wasn't the most deserving one to get the ATBB verdict, regardless of the fact it being the highest grosser then by a big margin. True ATBB's acc. to me are HAHK, DDLJ, Gadar & 3 Idiots. Not sure about Raja Hindustani's as it did great in interiors and footfalls of it were huge & KKHH doesn't deserve ATBB verdict IMO.
Anyways, it's good that they are becoming strict when it comes to verdicts but it was surprising to see HSSH as a BB, it shouldn't have been given that, semi hit is the correct verdict for Ra One, it doesn't deserve to be a hit. Don't have any issue regarding KMG's current verdict, it's fair enough.
