Srk-Kajol have worked in a lot of blockbusters together(Baazigar, Karan Arjun, KKHH, K3G) but DDLJ will always be recognized as their best to date. Debutant director Aditya Chopra so perfectly brings these two together at the back-drop of a realistic family setting that its hard not to fall in love with them. Its chemistry at its finest. For Srk it was his first "Raj" character(play-girl type guy with the right values and morals) which he plays to perfection. For Kajol, DDLJ was a career making movie. As Simran she's beautiful, sweet, sensitive and a bit stuck-up too. Thank god Madhuri didn't have the dates to work in DDLJ cuz no actress suits Srk better then Kajol. There are countless heart-warming scenes between em' in DDLJ. Each one of them is uniquely different and just as much fun to watch. The entire setting of DDLJ is very simplistic, which brings out that special "oomph" in their romance. The songs are first-class. The strong supporting cast of Amrish Puri, Farida Jalal, Anupam Kher and Satish Shah definitely helped the movie to become the classic as its now seen as.
Bottomline: DDLJ is 'romantic comedy' with Indian emotions at its peak. From the cast, chemistry, music, direction and the awesome pairing of Srk-Kajol....its perfect!
