Verdict - The question is not how, it is why was it made!
Firstly, who keeps a title like "Darr @ the mall". Thats just ridiculous.
Anyways, to keep it short, a mall is spooked and a bunch of people get in to spend a night or so there. It is a haunted mall that the chief security officer Jimmy Shergill is going to get under control.
Turns out, the place is spooked with an age old story of a lady & some kids being badly canned here. So fair enough, a horror film doesnt have to be the most original piece of work but atleast scare me.
The VFX are so bad that at times, I would be scared to be the bhoot. Predictable surely, the acting is also choppy and poor Jimmy is the only one putting in an earnest effort. Nushrat looks better than she acts and the motley crew are forgettable.
Anyways, this is no match to what I still call India's best spookfest, Bhoot. RGV, you had it sorted, now bring back your A-game. Skip
