The Apple TV app is a great example of half thought out design.

* You start downloading a movie. It doesn't show it downloading anywhere that I could see it. The only place I could find it was by going back * I had to login about 5 times * The Apple TV app is so new that you can't give Apple Feedback because the app isn't listed. * Supposedly I get a free year of apple tv with my new mac. I have no idea where to find that option to sign up. * When in you own library you can't seem to search your own library.

It just isn't thought through. And don't even get me started on the migration assistant. Buggy, and a poorly tested pile of crap.
