Not good at all.
As cool as the Rathtar set is, I don't understand the reasoning behind doubling up on what essentially is an obscure beast and an obscure character. I give Hasbro all the credit in the world for even taking a shot at this, but I would have favored the Probe Droid set in the mix. Not that the Droid sells any better, honestly. I don't know. Maybe things have changed. I hope we see the Wampa set, and others. A Fathier would have been neat, but I'm guessing that is unlikely now.
