Karthik calling Karthik

This movie talks about a very average guy karthik ( guess the director wanted to break out of rahul, raj image) so this guy is an invisible guy (not in actual sense of word)...just that no one will ever notice him...until one day he gets this call from another person who calls himself karthik and changes his life....    
            this movie is a suspense movie so am not gonna talk much about the plot....it definitely is interesting first watch....good direction by vijay lalvani....farhan akhtar is as good as u expect him to be....deepika adds charm of her own to the movie....the songs r wonderful...simply loved all the songs....full marks to shankar ehsaan loy for all the numbers.....i liked the movie coz it does make u sit upright, feel the horror n u wait to know the suspense....the movie is very well presented, romantic scenes are cute, will surely make u smile....
      all in all its different than the routine run of the mill stories....
