What bugs me about Netflix's movies is the seemingly haphazard way of distributing series. Right now, they have Mission Impossible 1, 3, and 4, but not 2. Starship Troopers 3 (Marauder) but not 1 or 2. I can watch Paranormal Activity 2 and 3, but not the original. Transformers 3 is available, but not the first two. It makes no sense.
Sometimes the studio's only want one vendor showing a movie at a time so they might remove it from Netflix to show it on Amazon Prime or Hulu for example. Netflix isn't the only company with agreements to studio's after all.
