No need to generalize. There is enough interest for women's cricket, but the only problem is that you can't compare with the men's game. There are a lot of fans for women's players such as Mithali Raj and Harmanpreet Kaur in India.
We can't say there is no interest in women cricket in South Asia there are many. People will take more interest if broadcasters air such matches live but they are not doing this. Seeing women cricketers carrying there kids along while participating in WC is really heartwarming scene.
I too like @UmerIdrees will try to catch the match live and share my opinion here. Thanks @ UmerIdrees for updating about that match.
