A buddy of mine bought me the first compendium of the Invincible run (first 47ish issues) and I LOVED all of it and wanted more. I felt the same way after finally watching the first season of the Amazon Prime show; I wanted more! They adapted the look and form so well.
I don't remember reading any solo comics for Atom Eve though, if there even were any. I remember her discussing her story but not much past that and her parents that she never got along with. So as far as I can tell, this is an original story.
And it freakin rocks.
I've been impatiently waiting for Season 2 like everyone else, and this just has me even more impatient. I loved this. It was very entertaining and the action was directed really well in particular. That Highway fight is by far one of the highlights of the entire series. It was legitimately intense, but it also surprisingly depressing and emotional.
This episode ended up being a LOT more depressing and emotional than I expected. We don't get a ton of jokes or one-liners, if any. It's still excellent though. As far as superhero origin stories go, this was so well plotted and made. The voice cast did an excellent job, as is expected at this point.
The only thing that bothered me was the long pauses between character interactions. I have the same issue with the first season of the series and it's somewhat prevalent here as well. It just bugs me.
Other than that, this was extremely well done. Kirkman and co. Are on top form once again in terms of writing and character development. Atom Eve was one of the very best characters in the comic run, and now she's becoming one of the best characters in the Amazon Prime content.
Amazing episode/special. Definitely watch this if you're a fan of the Invincible comics or the show. I really hope they do more origin specials like this!
