Comming to hotstar app it is the best app which helps you to watch many tv shows and if u you use android app u can download the videos and u can watch your favourite shows as many times as u wish
But beside this it is a very slow app some time it does not work properly and get hanged.
It shows only star plus channel shows and not other channels. It uses very wast amount of space in your phone or pc and not works properly.
But if they come up with all this draw backs it will be the best app
