Nop. They are nice way to consume stuff in a hurry, but I can only watch so many ants march around object on the screen before I want to throw something at it. Internet based compression can become very visually distracting. Also network congestions is a real mood breaker in a tense scene. Mobile devices are useless, If I watch a film on my phone I have to recharge it halfway through, so it becomes less mobile. So I may as well watch it at the cinema, or on TV.
