My favourite of the season. Beautiful in HD. That shot of the Enterprise approaching Starbase is a stand-out of the entire seven season run for me.
Nice observations about the Bynars - always wished we'd see them again. Perhaps they served some time on Memory Alpha to pay off their debt to the Federation?
My only nitpicks - regarding the encryption key. The Bynars only wanted Riker, Picard being their was "a fortunate happenstance", how would Riker have entered the encryption key in tandem by himself? Also, why use an encryption key at all? They wanted their world to be saved, so why make it more difficult?!
