Another good reason why Khoobsurat can never let you down... Rekha (she won her first Filmfare for this one). She is the heart and soul of the movie, breathing life into the script at every turn. She is the beautiful here, the one who makes life worthy of living. She negates all the drudgery, all the seriousness, to ring in mirth, laughter and jollity.
So much as the family members hate Nirmala's ideals, they don't really have the spine to raise their voice against her diktat. So they meekly behave themselves and wish in their heart of heart that someday they would be rescued from this labyrinth of rules.
As much as I feel the songs (music by RD Burman) contribute to the story, I think Saarey niyam could have been avoided. It is kind of gimmicky and stretches the length of the film for nothing. Since Manju already proves to the Guptas how it is okay to not follow rules from time to time, with her actions, this song, I feel, is redundant and reiterates what she already has said.
Khoobsurat is a film that you watch when spirits are low or when the idiot box is airing nothing good. Trust me, this film, bearing the signature stamp of the master director Hrishikesh Mukherjee, will surely make you smile... and laugh out loud!
