Kussa Kursi ka- and- Andhi- are among banned movies. I saw these two movies and found both entertaining and nice. Kissa Kursi ka is an artistic movie and uses symbolism. Just one woman starred by Shabana Azami- represents entire people (Janata). Many movies are banned just because those in power dislike these for one or another reason. Some like 'water' are banned because of opposition by religious groups .
