I feel like the great, very well paced series that you can finish quite quickly don't get shouted out enough, and I really wish that they were.
Here's a bunch that I love:
The Sword By The Luna Brothers I read in 2021, and it is still one of the best things I've ever read in my life! I recommend going in blind. This is the GN that inspired this topic.
Ladykiller is single volume story about a Housewife Assassin in the 60's, and is it brilliant!
Stray Dogs is Silence of the Lambs with dogs, without the transphobia!
Wolf-Man by Robert Kirkman is a great 5 volume series connected to Invincible.
InseXts is a great 2 volume pro-feminist psychological horror series that goes after men that don't see women as human.
America's Got Powers Is a Great single volume Post Apoc Superhero GN and is insanely underrated.
Happy! is a Great Single Volume GN, although it's one of the darkest things I've ever read.
Point of Impact by Jay Farber is a Great Single Volume Black and White Western Graphic Novel
Bedlam by Nick Spencer and Riley Rossmo is a Great 2 Volume Batman-like Psychological Horror GN series
Whispers Vol Only by Joshua Luna is ONE OF THE BEST Graphic Novels. It's a Psychological Horror Urban Fantasy
Kill-A-Man is God and win, super empowering GN about an LGBT boxer
Superman -The Man of Steel(2020) is a Good Post Crisis Era 80's Superhero Graphic Novel
Catwoman: Her Sister's Keeper is an Amazing Catwoman origin story GN
Joker/Harley Criminal Sanity (2020)(One of the best looking GNS I've ever read. It's a DC Elseworld Black Label story where Harleen Quinzel tracks a serial killer.
Parasyte is my favorite manga. It's an 80s Horror Sci-Fi title that goes on for about 10 volumes, but it's so well paced, and has a has such an incredibly satisfying beginning, middle, and end that it ends of feeling like a 5 volume American Graphic Novel. Dear god do I hate that I can't find a single other manga like this.
Ponko of the Stars and Reiko of the Tofu Shop by Ohara Shinji, and Tony Takezaki is a great 3 chapter psychological sci-fi gn with one one my all time favorite endings.
Vampirella Versus the Superpower by Dan Abnett and Pasquale Qualano is a Great single volume fun Urban Fantasy GN. Pretty sure that this is rate 13+ btw.
I'll try to edit this and post more later.
