In a nutshell, the show was cancelled--dead. The story had been wrapped up in the two episodes preceding the finale. Right or wrong, Berman and Braga decided to end the show with TATV. It's over now, time to move on.
That said, I don't think it's all that bad.
Just cut all the parts with Riker and Troi out of it, add a few minutes on the end instead in which we actually see the Federation Charter being signed and you might have a reasoanble episode.
