Lekar Hum Deewana Dil depends completely on its lead actors. Also, Arif combines the sparkle and adrenaline rush of impulsive liaisons with serious take on relationships, giving ample scope to the first-timers to make an impact. Armaan has the charm that should help him establish a substantial fan-following, but more importantly, he is definitive and confident for someone who's facing the camera for the first time. Deeksha, who has featured in a couple of South Indian films prior to this film, has a pleasant screen presence and also handles her part confidently. In fact, she underplays the dramatic portions delightfully. The film has several wonderful moments and genuine sparks that stay with you. The film should appeal to its target audience -- the youth but would have done much better for itself had it tried to find its original voice, instead of pandering to a vague idea of what sells when it comes to love stories.
