Scarlet. Or maybe Scarlett? I can't exactly remember. But it's about this young woman who decides to start a revolution after some shit goes down. It's an interesting story, even if there are bits of unnecessary violence. Plus they did this thing where the lead character talks directly to the reader that's kind of interesting from a medium perspective.
TINTIN! It is just like SO EPIC! The drawings, the stories, the characters, everything, was beautifully done by Herge!!! It had SO many things that recent graphic novels forget to include ^^ THE CHARACTERS ARE UNFORGETTABLE! MAY HE EVER REST IN PIECE!
Probably a tie between the Blue Beetle series (Jaime Reyes) and Watchmen. The Blue Beetle series was just interesting and he's probably one of my favorite super heros (DC-wise) Watchmen just speaks for itself, the art and story in that movie is amazing.
1.Bone (Jeff Smith )- Though I only have the first book I love this visual novel. The characters feel so real and relateable and there is an excellent plot to go along with it. Give it a check if you have the time!
2. Smile (Raina Telgemeier)- This novel doesn't have a lot of action or drama in it but is still very good because of the moral lessons it left me with. I from time to time read it over out of fun.
Probably a toss up between the Bone series and Sandman: Dream Hunters. Though I guess Dream Hunters isn't a graphic novel per se... it's more a story book for adults. But it's worth getting, imo; the artwork in it is gorgeous. I got a big gift card for Chapters not long ago and it was the first book I bought with it
Can't really say there's one graphic novel above all others but there are a few like that.
Scott Pilgrim-It's just a good story. Real believable characters with realistic problems. I've never seen a more realistic character than Scott Pilgrim, yeah he's kind of a douchebag but there's a REASON, he has emotional baggage and is emotionally unaware. He evolves as a person throughout the story. The allegory which is so complex and overlooked. Give it a couple years, they'll be writing essays about the series.
Nausicca of the Valley of Wind- Just a sweeping epic, far superior to TLotR. The characters are real, the story is vast and epic, and it's not some weak pathetic princess, or some raging pacifist, it's a real hero that makes tough and terrible decisions to try and save the world. The overtones of environmentalism are not pedantic, there is something to be truly understood about the book's message.
Spice and Wolf-If you have never read a single GN in your life, you'll still end up loving this story. The characters are real, they have a complex relationship, the economic intrigue is interesting and accurate, the art is very solid. If I had to make someone like manga with just one book, I would bet on Spice and Wolf.
