Barry and Patti’s relationship comes to crisis, Jay and Caitlin’s intensifies, Joe tries to have one with his son, and Zoom looms.

Meanwhile, the team tries to track down the villain known as the Turtle, whose powers might assist them in the coming confrontation, and someone makes an unexpected return.

High Points

The episode took, perhaps, the silliest villain in the Rogues Gallery and made him work. He was even menacing. We’re also reminded of how intimidating Zoom can be, though it makes me wonder why (in world) he’s letting his plan unfold so slowly.

Low Points

The science was predictably bad, but at this point we can let that pass, in part. A bigger drag on this episode was the often ponderous and obvious discussions of relationship. The very scenes that should show the series’ heart turn it, in place, to the Slowest Ep Alive.

The Scores:

Originality: 2/6

Effects: 5/6

Acting: 5/6 The acting was generally good, despite some turgid writing of relationships. Jesse L. Martin and Shantel VanSanten stood out, and Teddy Sears has grown more impressive as the Jay Garrick Flash.

Story: 4/6 The stories held together. Some of the relationship drama, as I’ve noted, was heavy-handed. The Turtle, meanwhile, had to easiest lair to track in criminal history. One wonders if Wally is right about Central City detectives.

Emotional Response: 4/6

Production: 5/6

Overall: 5/6

In total, “Potential Energy” receives 30/42
