I didn't like the episode for the most part. It felt like a lot of filler minus the last 10 minutes, for me it's the worst one all season. Usually pre finale episode stuff is jam packed with stuff to keep you hyped.
Edit.
Also they had Iris hair looking real horrible.
I agree, it wasn't that great of an episode outside of the last 5 minutes or so. Also...
Why isn't there a real push for Cisco to reach his full potential?
Why are they dragging out Wally and Jesse becoming meta humans?
Why didn't Barry make any real effort to save his dad?
