I couldn't find enough to watch after the first day. Perhaps the selection is better now than 6 months ago, but I wouldn't have paid a dollar to have the service then.
However, I'm not the type to watch movies over and over. I'm not one to watch old movies just because I can. And I completely don't understand why you want to try and get friends online together to watch a movie together. Just fire it up and watch the dang thing whenever you want. Plus, if I'm watching a movie at home, I like to use the pause button for the restroom/phone calls/dinner break/etc.
I guess there's people that will use it....
