The Flash: All 9 seasons ranked from worst to best

7. The Flash season 4

Hoping to leave its days as a speedster-only show in the past, The Flash attempted to introduce a new type of big bad in season 4. Unfortunately, that brought with it a whole new list of problems that made the speedster fatigue look much better in hindsight.

While Clifford “The Thinker” DeVoe was played remarkably by Neil Sandilands, the story did not serve the character well. Or maybe it served him too well, as he eventually became far too powerful for Team Flash to overcome, resulting in a pretty hopeless season with too many episodes that saw our heroes defeated by the villain over and over again.

To make matters worse, DeVoe’s plan relied on a group of new metahumans, meaning that we got a heap of villain-of-the-week episodes that lacked the heart of the show’s previous ones and almost always ended in a death.

There’s an irony in the fact that this season’s shining light is an episode centred around speedsters, as “Enter Flashtime” stands above everything else season 4 did and remains one of the all-time greatest episodes that The Flash has ever produced. And that alone makes this season worth watching.
