It's a movie rich with Indian culure backed up with a strong patriotic message on there's sacrifices made for love (for your country, name or your loved ones) and for freedom.
Needless to say, an amazing script and the level of detail in Indian culture (Dance, music, jewellery, fashion, architecture) is off charts and deserves special praise. The love stories that are embedded within the series is an added touch.
I didn't find the music of the series to live up to the Indian standards but everything else was top notch.
