There's a trick in mass filmmaking to balancing what the audience wants/expects to see with what the directors and writers and heroes/heroines want to do. When it works, you've got Sholay or Mr. India and when it doesn't… well, hello, passion-project flops like Joker, and hello, crass lowest common denominator schlock like Humshakals.
Which brings me to Kill Dil. The trailer looks sharp and nicely unironic and I love the casting but… it is a Shaad Ali film. I'll be very curious to see what--if any--lessons he learned from the failure of Jhoom Barabar Jhoom, a film I remember as being overly smug in its meta-narrative tone and, worse, just plain boring.
If Kill Dil aims for a Bunty aur Babli level of meta-madness with a big dose of heart, plus a dash of the "modern" masala throwback style, I'll have nothing to complain about.
