Martin synthesizes a way for Jax to retain superpowers, albeit not his original ones. When he describes them, Jax suggests that he's turning him into the Marvel superhero Spider-Man. He questions whether he'll have Spidey-sense, but Stein tells him he won't, mockingly calling himself "the Spectacular Sticky-Man." See more »

Barry Allen: You know, I mean, I've been in love with Iris since I was ten. How am I supposed to fit all that love into one vow? I've already written thirty-eight pages. Single-spaced.

Here is another biased review. I hate the wedding subplot, I think it has been draining life out of the flash series, so having so much of this crossover focus on it was annoying. I would never call them "the most perfect couple in the world, it is like the writers have an idea of who these characters are but that idea is noticeable different from the characters you seen on screen on weekly basis. Dialogue was 5-10% good, rest of it was forcefully peppy or outright painful.

CG was poor, it is unsurprising for a TV show budget yet I got my hopes up for a bit, then I saw supergirl uppercut a dominator and my hope took a dip but the church fight was good.
