I think what I loved most about this episode is the flashbacks they showed.
They were perfectly timed in each if the scenes. Some were sad, some were funny and some were well simply intense.
The episode was perfect because it brought back so many memories from the entire series, not just from senior year, although seeing some of the flashbacks made me long to have Brenda and Dylan back together. What was great about this episode as well was the fact Andrea was stressing about her speech and that suited her character to a tee and Brenda was trying to decide to leave behind her life and friends in Beverly Hills and return to Minnesota. All and all one of the best first parts to a season finale (even though when the episode was first aired and released on VHS it was really one episode). This BH, 90210 fan gives it TWO-THUMBS UP :-)
