I absolutely adore this movie! I've noticed that films produced by Shah Rukh himself tend to end up in my TOP-10 list -- Asoka, Main Hoon Na. And the same happened with Chalte Chalte -- it's definitely one of my favorites now, right up there with Kuch Kuch Hota Hai and DDLJ, if not better.
I really love the SRK--Rani jodi. They both gave great performances and looked really convincing and sweet as a couple. I was so rooting for Raj and Priya to be happy and together in this film that the viewing turned into a very emotional experience for me, which I didn't expect at all, having read some rather lukewarm reviews.
Rani looks absolutely stunning (well, as usual) and very feminine. Shah Rukh oozes charm and charisma in a really complex role. I personally just loved his character -- with all his flaws and insecurities. Together they are just way too cute.
I liked how realistic and unpretentious this film was, liked the drama in the second half, loved the music and all the songs. They are all outstanding.
Overall, I think it was a very well made film that really endeared itself to my heart. Not one boring scene (except for the very beginning -- I really thought that subplot could have been done away with), and Johnny Lever was great -- hilarious in most scenes (in an unusual role), serious and adding to the drama in others.
I'm just grateful that this film exists.
