No, it isn't redundant at all. When I went to college, that meant that all of my high school friends became long distance friends for the most part. We always watched some shows together beforehand, and we still do; the only difference is we have to use skype group calls. Do you realize how annoying and unintuitive it is to all load up the show/movie on hulu/netflix, wait for it to load, then countdown the play button and hope we're all synced up? It's too much hassle.
Honestly, this is the service I have always dreamed of having. The only downside is you have to have the camera on, which is a bit dumb, as we usually just voice chat; but that won't be a problem a simple ripped sticky note cant solve
Needless to say, I'm excited for this app!

It opened just fine for me without any issues on my ML MBP 2011.
Sounds like a lonely way to watch a show.
