Critic Reviews for Welcome to Earth

Whereas the overall message of the episode feels like it should be good, the elements sort of flounder when they they're examined individually.

Between the M'gann Morzz reveal which punctuates this episode, and the My President is an Alien moment that happens just minutes earlier, this season of Supergirl is keeping the stakes high and the tension up until the very last minute.

There was a lot of CatCo stuff going on in tonight's episode.

It's a nice breath of fresh air in a world of superhero shows dominated by misogyny, chastisement and masculinity. You're doing many superhero things right, CW. Keep up the good work.

Maggie Sawyer's debut was fantastic.

...a pretty superb episode of the series, from the allegorical takes on diversity to the introduction of Maggie Sawyer.

This week's Supergirl introduced several intriguing new characters and set the stage for big conflicts to come.

All in all, "Welcome to the Earth" is a fun, moving hour.

Supergirl may have undergone many changes between season 1 and the first three episodes of season 2, but it's proving to be as resilient as the Girl of Steel.

There is so much of Supergirl as a series that's applaudable, but one wishes that the writers would slow things down a bit and perhaps make it a little more nuanced.
