I'm really not sure what, if anything, the finale format brought to the series. Perhaps they were bored with the tasting-like presentation of the other seasons. For me, in my finale, I would want the purest expression of each chef's ability without gimmicks/confounds, so a tasting presentation would seem ideal while acknowledging that there'd never be a perfectly equitable format.
The endless flashbacks/recapping was also a bit obnoxious. It felt like a 20-30 minute episode stretched to fit a hour format.
Tinfoil hat: How does judge voting work on this show? With the framing of each episode, the intent seems to be to display the maximum amount of drama while foreshadowing a contestant's downfall. In the finale, it seemed like Kristen had the second round, but for the sake of prolonging the episode the round was given to Brooke. Had this happened, and Kristen won the third round, would they have ended the finale? It seems very unlikely, so the voting seems a bit orchestrated. Then again, I'm happy with the results, so what do I care?
