The clothing difference is deliberate because she's supposed to have returned from the US when the movie starts :) And yes, I love that stomping off bit.

Hm, off the top of my head, some of my favorites: Dor (lovely female friendship), Mr. and Mrs. Iyer (serious but hopeful), Lagaan (period film and has a lot of cricket in it, but the cricket is almost a metaphor, and also, the songs are awesome), Taare Zameen Par, Astitva, Omkara (adaptation of Othello, and IMO, skilfully done), Anand (older movie, tear jerker). I really enjoy all of them. I'm not sure about Anand, but the others should have subtitles.
