Just finished watching it. Not as good as "All Good Things" for a finale, but still entertaining, emotional, and action-packed if a little bit of familiar territory. You definitely get a sense of the camaraderie and friendship among the TNG actors and characters. If you were disappointed by "Star Trek: Nemesis" as a finale for the TNG crew, you'll find this season and finale to be a much better send-off.
The final season was great the show as a whole, was very mixed. I feel the show will be remembered fondly enough, mainly for the 3rd season, and fans tend to be forgiving of the bad aspects of Trek as the years pass.
