I have a laugh every time I see their "Recently Added Movies on Prime" section and find films from 2007. Or their "Popular|Trending Movies on on Prime" and see films with a <5 score on IMDB. There is no reason I would keep Prime for its movie offering! In the last six months they've added more and more sponsored offerings too, which is _really_ annoying -- I mean, I'm a subscriber, stop advertising to me.
I hate it when I miss the start (separate annoyance: seems often that audio takes a few seconds to start? Maybe that's the Shield's fault rather than Prime's) so I rewind, and then it hits me with the advert again...
