I think its an ok app. Nothing spectacular compared to Hulu or Netflix. No Apple TV functionality currently either. It would be great if it worked seemlessly with Apple TV but right now you have to play from other device using mirror to Apple TV. Quality is lost and some devices cause letter boxing. Id give it 4/5 if it would air play without mirroring. 5/5 if it just gets straight to Apple TV so I can cut out the extra device.
