Chalk N Duster’s prime aim is to highlight the plight of overworked, underpaid schoolteachers and the need for substantial perks or privileges.A respectable enough idea that would make for a compelling viewing under better hands but director Jayant Gilatar’s sloppy ‘tribute’ never ever develops into anything noteworthy.Shabana Azmi’s Vidya Sawant, who plays a committed Mathematics teacher in a private school, is the sort of life-altering ideal, students are likely to remember and revere till the end.Her close colleague Jyoti(Juhi Chawla) specialises in Chemistry and mimicry, which she doesn’t teach but appears to be her only distinguishing attribute in Chalk N Duster’s loose narrative.Others like Jackie Shroff and Richa Chadda are wasted in wishy-washy roles that don’t add up. Also, the movie was not promoted the way it should else it would have gained much more audience and applauses.
