Critic Reviews for Crisis on Infinite Earths: Part One

Its first 10 minutes are some of the most exhilarating superhero TV I've ever seen.

No amount of watching, reading, and speculating truly prepared us for the heroism, the tears, the sacrifice, and the cameos. Oh, the cameos! And it's only the first hour, people!

Overall I thought it was a great way to kick it off.

By throwing everything they have at a specific series of episodes, whilst tying up certain narrative loose ends Crisis is entertaining without feeling overwhelming.

There are so many great DC cameos and homages within the first ten minutes of the episode. They're the perfect way to tie the universes together.

Crisis on Infinite Earths' balancing the big with the small really drives home how much of an advantage having five hours to play with your story can be if you do it the right way.

We have finally arrived at Crisis Arrowverse Fans, and, oh man, did it live up to the hype.

Dec 9, 2019 | Rating: 4.9/5 | Full Review…

"Part One" of "Crisis on Infinite Earths" was relatively modest in its use of Arrowverse's massive superhero cast, which I think was a very clever choice.

That was highly unexpected.
