Not really a problem. First Friday of December has seen good legs in last couple of years but they had Xmas release failing. That said, there is a potential to do ₹250cr Nett on Non-Holiday week if WoM & hype are good so it mustn't be a problem.
Problem is, it won't have 2nd open week as Maidaan is releasing. That need to move, then it can get 3 open Weeks before Laal Singh Chaddha & if LSC don't get good WoM, may get Xmas legs in late run.
Sanju did ₹320cr in 3 Weeks, Brahmastra will be happy with that.
