I really love Percy Jackson and I really enjoy graphic novels, so I'd thought this would be an easy, nostalgic 5-star read for me! It's also been a crazy long time since I've read the original series as well, so I thought the distance would mean I wouldn't be comparing the two too much. In the end... I think the graphic novel lost a lot of the charm I loved from Riordan's books (namely the humor, tbh), and I don't know if I'll be reading the rest of these...
I get that graphic novels can often feel a lot more rushed than the books they're based on, and this is definitely true here. However, I did expect that going in since the series was adapted 1 to 1, instead of multiple volumes per book (like with the Maximum Ride manga), so I didn't necessarily feel this hindered my experience too much. Yea, explanations were a lot faster and there was almost no build up between anything (kinda just a bunch of action scenes tied together), but I didn't necessarily need all the exposition to enjoy the book because I had read the series already, I knew the characters already. (I do think that first time readers should start with the books though, this graphic novel is way more plot than character background/development, and I feel like you miss out on a lot).
My biggest issue was the lack of humor though. Part of this comes from the style of the comic itself, it's a serious style of art and that definitely affects the tone of what you read. But beyond that, there just wasn't any of the jokes that Riordan is known for. I missed the wacky chapter headings (one of my favorite things as a kid), the character's barely joked around with each other, and overall the entire adventure just felt way too serious. It's honestly as if it was supposed to be aged up to YA or something and in order to make it feel 'older', they cut all the jokes. It made the characters feel more like shadows of themselves, and I didn't end up liking the dynamic they had together at all in the end.
I probably won't be continuing the graphic novels, but I definitely want to reread the actual books even more now!
