When I saw this episode when it first aired, I was blown away. It was the best 2 hours of television that I have ever seen.
It takes place four years in the future, which I thought was a great idea. It let us see our favorite characters in the real world after college, and it was good.
Joey's now an editor, Jack's an English teacher, Dawson is the writer and director of his own show The Creek, which was based on the indepedent movie he made during the second season of the show. Jen is a mother to a beautiful baby girl, Amy. It's said that her boyfriend knocked her up and then left her. I would assume that the boyfriend wasn't Jensen Ackle's character, who we last saw her with because he seems like too nice of a guy to do that, but they never really say who it was.
The gang is in town for Dawson's mother's wedding, and the first hour has to do with the death of one of the cast, which is very heartbreaking, I cried many times, while the second deals with the love triangle that is Pacey, Joey and Dawson.
I loved the finale when it aired in May, but when I heard that there were deleted scenes in the dvd, I had to buy it even though I had the other on tape. It was well worth it, if just for the return of Meredith Monroe as Andie. The best addition was at the very end when they show clips of all of the most important scenes of the last 6 years. It's very touching.
I would definitely recommend buying this whether you saw it when it aired, or if you have yet to see it.
It is an excellent episode.
