I did like Sue Dearbon, but it would be nice if the writers remembered that the show is called The Flash, not The Iris or The Elongated Man.
As much as I enjoyed the episode, this was my biggest draw back. It feels like since the show came back there hasn't been nearly enough Flash for my liking. It's like the writers told their lead characters in Arrow and Flash that they could take some time off. Now I know Crisis was a big crossover event, but I wonder what the scheduling was like taken into account that they did have over a month off from Crisis III to the midseason premiere. Hopefully with the return of Grodd next week, it will be a pretty Barry heavy episode.
Other than that, I really enjoyed this episode last night. Much better than the previous week and they nailed the casting of Sue. The only familiarity I have with Sue is a podcast that I listen to has been talking about her a lot and I really loved the chemistry between Ralph and Sue. I'm looking forward to seeing her return. I also liked the reveal at the end with the new Mirror Master. So far in the last 3 years this has been my favorite arc since the show came back from the midseason break. I hope they can keep it up.
