Some people like me still prefer Quality first. So Blu-Ray is the besst way to watch movies at home.
1080p streaming is no where near the quality of Blu-ray and the audio not even close.
But like I said if you want Quality watch Blu-Ray - if you want quantity or crap quality go streaming.
Until streaming is 50mbps blu-ray quality not too interested. (before you ask I have a Fibre internet with 72mbps connection).
