My rating of this app is not given relativity. I may give this app five stars but how will an onlooker gage the reliability of my rating if they do not know the rating I have given another app. An onlooker may be able to find my rating reliable if they agree with the ratings I have given other apps. Sure this system takes into account the majority of peoples ratings but what if a majority of ratings are unreliable. The quality of my ratings should be valued as much as the quantity of ratings given. That being said, I would give the HBO app five stars because you can create a list of content to view. This STARZ app only allows a list on the Apple TV version.
