Critic Reviews for Cause and Effect

It's a very meta episode, and I'm not talking about metahumans.

As much as I love witnessing Barry and Iris fall in love all over again, I also want to understand more about who she is on her own.

I loved that HR and Tracy kissed in this episode. I found their entire flirty subplot incredibly charming.

For the entire season, we have been dealing with the cause and effect of Flashpoint. I'm kind of ready to move on.

The subtle foreshadowing game was on point.

Such a breath of fresh air... It's no coincidence that the best Flash episodes this season have been the ones to fight back against the darkness and focus more on lighthearted comedy.

But leave it to The Flash to hold on to a few surprises.

We learned a whole lot about Savitar's origin this week, but it's still insanely confusing.

The amnesic Barry Allen was funny, I'll give the writers credit for that.

Where it's at right now feels like a necessary retrospective on both the recent darkness as well as the show's initial whimsical nature.
