The gang comes together for Barry and Iris's wedding, but the ceremony is crashed by villains from Earth-X.
This was a really great second half that did a good job of having the mains story part in the third part and then just wrapping everything up in the fourth part. All the moments on Earth X we're really well done with how they took the ideas of each of the characters and introduced some new ones and just working through a whole plan of how to escape back to Earth One. I really enjoyed their introduction of The Ray and how they played him into everything and just how well he sort of fit in with the rest of the group. Then the reintroduction of this new version of Captain Cold as Citizen Cold was interesting where he's from Earth X and doesn't know any of the other people. Then everything that went on with Kara and everyone stuck in Star Labs that didn't get stuck on Earth X was interesting with how they eventually managed to free Kara from the red light altering her powers and how they finally brought the rest of Legends into the fight. And it was fun that they did again have a little nod to Ray's Superman past. It was really interesting who out of villains in the character's past they decided to bring into this with them reintroducing Metallo, and Red Tornado, as well as a few other villains, was interesting to see how they fit them all in and how they actually had other heroes fighting against these villains instead of Supergirl. Then just the whole final fight scene between the heroes and the Earth X versions was interesting to see how it all played out. It was a little disappointed that it definitely looks like they ran out of money because the visual effects didn't look as good as they did in the previous parts. But still, all the fighting and how they decide to end the story for each of the Earth X members was very interesting to see. The ending of the fourth part I really don't care for and it felt really kind of unnecessary and could have been so much better if they just cut it out or shortened it. Because I did like that moment of Barry and Iris finally going through the whole ceremony of getting married even though it wasn't necessary but then having Felicity barge in there and make it about her by saying that she wants to marry Oliver as well was just really annoying and unnecessary with how it looks like in the next Arrow episode they're just going to get married again. So that ending just felt really weird and unnecessary and I felt like I could have ended a lot better if they would have just ignored that part all the other. And just overall this was a really exciting and fun second half to the crossover and I can't wait to see what they might do next year.
