Cisco's idea on how to make Barry faster than Zoom involves a meta-human criminal known as The Turtle who can steal kinetic energy. The team tries to catch Turtle, but when unsuccessful, he retaliates by kidnapping Patty. Meanwhile, Barry's recurrent nightmares feature Zoom threatening Patty's life; while Iris encourages Barry to tell Patty the truth about his identity, Dr. Wells tells him it would be a mistake. And Wally's bitterness blocks Joe from knowing him better. Written by Andreea D/edited by statmanjeff

Slow it down
27 January 2016 | by tenshi_ippikiookamiSee all my reviews

"The Flash" has a down episode, as "Potential Energy" is far from what the show can offer.

As the Flash seems unable to gain more velocity, they decide to catch a meta-human called the "Turtle" because he can choose what or who to make move sloooower. They think that if they know how to use his power, they can take the speed from Zoom. But the episode doesn't seem to know what to do with Turtle (Battlestar Galactica's Chief Galen Tyrol's Aaron Douglas, doing a good job; it's nice that the show keeps bringing popular actors to play the meta-humans) and his powers are not well developed (or maybe not so interesting).

But it's not only that. Wally West's storyline seems taken from the "how to make your first script" book bin discount and is quite ridiculous, as it makes the character quite lame. And how the show deals with Patty and Barry relationship is also not very smart writing, and lame too.

The show is great, and all its strengths are in this episode. Too bad there're a lot of unusual weaknesses too.
