The Yesterday's Enterprise commentary is a lot of fun to listen to. RDM is right, this should have been the TNG movie, with the original crew meeting the TNG crew. He was also right and so was Ira this would have made a really cool 2 part episode if they had the time to think this all through, but there was such a lack of time working on scripts this season
The lack of time doesnt seem to be a bad thing. AGT was also written in a hurry, while GEN took one year. I guess if you have no time, the writers and producers dont question bold moves in a story so much, so instead of taking them back/smoothing them out, they are left in and as a result the story has some edges that make it special.
