It's easy to tell that there was a sense of rejuvenation and revitalized energy surrounding everything. The plot wasn't dark, but the emotions ran high, and were honestly the best parts of the episode.
As we pick up six months later, the team has been reorganized, with Iris taking on a strong leadership role. This is the first positive change of the new season.
I was most pleased with the character development that Iris was given during this episode and the fact that the Flash writers are finally paying attention to her.
