I mostly prefer Hollywood movies..and not much Bollywood films scares me but 1921 scared the hell out of me..Unpredictable scares is full(for that I got irritated a little)but its scary.. Its entertaining ,I didn't find it boring ..also when the love scenes was there ,I never forgot this a horror film..Too many different ghosts makes,it very unpredictable as we don't know which and what face is going to pop out when..Specially the dark ghost with eyes glowing is from Hollywood films like lights out,Anabelle 2(that ghost is actually the real star which really scares )..Zareen was very good(I didn't except,but its really nice to see one of my fav actresses impressed me after watching Hate story 3,Aksar 2 ..I didn't expect an empathetic acting )
