Yeah, I think you missed my point. It doesn't matter if "most of the crew" is different. The command crew (the main characters) are exactly the same. What are the odds? They could've at least shuffled them up a bit.
No you missed the point, actually. It's that, or you are just being intentionally confrontational. And of course it matters if most of the crew is different because it shoots your theory down. The command crew is made up of what is supposedly the best of the best in starfleet, being that the Enterprise is the flag ship in both timelines. Picard was the best captain who gets appointed the flag ship. Naturally he is going to make similar crew selections.
