Critic Reviews for Welcome to Earth-2

The Flash at long last brings our own heroes to Earth-2, on a mission to defeat Zoom and rescue Wells' daughter Jessie from his clutches.

While the episode started out with great promise, it eventually devolved into the same storyline we keep seeing over and over again. It's another instance of Allen's impulsiveness getting the better of him.

If you need definitive proof that The Flash Season 2 is capable of meeting and even exceeding the heights of Season 1, look no further than "Welcome to Earth-2." This episode easily ranks as the best of the season, and quite possibly the entire show.

The only times "Welcome to Earth-2" seemed to stumble were in falling for the exact trap Jay warned Barry to avoid, losing sight of the mission at hand by getting lost in the allure of another world.

This was an absolutely insane episode of The Flash, and that's saying something since this show is normally fast-paced and full of Easter eggs even on a relatively slow week.

Overall, though, this was a fun one, and badly needed after the show had been bumpy for a little while, between the obligatory Legends of Tomorrow set-up, all the angst over Patty, Wally, etc.

Grant plays Barry's intense joy over the unexpected gift of speaking with his mother against his deep sorrow perfectly.

Even though two earths are better than one, I'm not sure Episode 13 was a great episode of the series, despite it's absolutely tremendous fan service utilizing the actors and the characters in very unique ways.

Jul 27, 2018 | Rating: 4.5/5 | Full Review…

It's interesting to consider that, on the far more advanced and almost utopian world of Earth-2, the Flash is pretty much a speed addict. This adds some much-needed texture to Jay's character; he has felt like a cardboard cutout since his introduction.

Jul 26, 2018 | Rating: 5/5 | Full Review…

Welcome to Earth-2 delivers such a jam-packed episode of Easter eggs, role reversals, and enough repercussions to affect not just the CW-verse of DC shows but indicate just how a certain superpowered girl on CBS could factor into things.
