I am using hotstar from last 14 months. And I am sharing my personal experience with you. This is very good app to watch cricket or some exclusive movies for those persons ( students ) who do not have TV .
This has a facility to watch online movies or anything according to your network connectivity and data consumption. As you can watch a movie of 2 hrs in 500mb.
You can increase or decrease the rate of data consumption according to your need and choice.
Very good for students and all.
Love this app
