20 Best TV Episodes Of 2016 

20. Welcome To Earth-2 - The Flash

The Flash hasn't had the best of years, especially in comparison to its joyous first season. Things got a bit darker in Season 2, and a few issues meant that a lot of it felt pretty lacklustre.

That's why Welcome To Earth-2 felt like such a fun ride. Well, and because that's exactly what it was.

Heading over to the parallel universe was a big leap for the show, but they pulled it off with aplomb. It was the series operating on all cylinders, with some silliness, lots of fun, fast-paced action, and a ridiculous amount of nods to both the series and the comics.
