Its been so long since Ive watched anything that wasnt pre-recorded that I was initially annoyed by the inescapable commercials... but they are not quite so bad as the consensus seems to imply. The breaks only seem to be about 2 min long with 4-5 mini-commercials that fill that time. Whats irritating is that it seems to be the SAME 4-5 mini-commercials over and over again.
Whats far more annoying is the lack of any kind of playback controls other than to pause. No rewind to skip back and obviously no way to skip ahead (otherwise the commercials wouldnt be a problem)... which makes me want to ensure I never miss another broadcast recording.
As far as being watchable or not goes... yes, it would be much nicer if you could cast it to watch it on a regular TV instead of a mobile screen, but I must say that the playback was very steady, clean and rather high-quality. I just spent about three hours catching up on one missed episode of FtWD & its associated Talking Dead... and a bunch of bonus/extra stuff I hadnt caught.
Is it worth putting up with the annoyances to watch missed episodes? Yeah, it is. Is it worth using to watch the little bonus scenes & extras? Absolutely, because those generally dont have commercial interruptions - those seem to be saved for full episodes.
Does it make me want to take extra care to make sure I record episodes when they first air? You betcha! Do I want to use it routinely? Not really... but its better than missing episodes altogether... if only marginally. It is definitely better than some of the other streaming video apps Ive used (like, for instance, the STARZ app, which was truly bad enough to make me want to drop STARZ).
