Storyline-wise this is a totally acceptable episode of The Flash... Moving forward, the show is in a very exciting spot for fans. Jesse Quick & Kid Flash both have received their powers and Wells is in quite a precarious position as it looks as if Barry is gone and Wells is responsible.
As exciting of a chapter as The Flash is currently turning to, it's not without its problems... And I'm compelled to say something as there are times when this show makes me want to bang my head on a brick wall. For one, The Flash (for the most part) has a great cast but Iris is like a huge anchor weighing them all down. Her movements are almost robotic, she looks uncomfortable during scenes where she has to channel extreme emotion, and watching her struggle to find the right emotional note she'll take it to another level by making awkward movements... It's like she doesn't know what to do with her body. Which begs the question... Where is the director to give her some direction?!
I also wish they'd turn down the quintessential 'whiny superhero' bit that Barry has been going through as of late... It was a huge turnoff when it was such a big focus of the Toby Maguire Spider-Man films. If you have to attack it, do so and move on, it's become a tired cliché in the genre and one I really hope to see less and less of as the genre continues to explode.
Please excuse my rants... I feel like The Flash could be great and at times it is, but it gets in its own way. There is a tried and true formula you see again and again over at The CW and sometimes they let that get in the way of the betterment of the show.
