I've followed John McCrae/Wildbow's works for a while, and I've read all of them with the sole exception of Twig, so it's funny to see it pop up here. I made a thread for Ward back when it first began, but it did not take off at all.
Worm was something I really enjoyed while reading in a giant binge, getting on to it towards the last few arcs. The ending was and still is incredibly hype, and there's a lot of great moments in the story. As others have said, it does suffer by nature of being a serial novel, meaning the pacing is screwed up in a lot of places, but the huge cast of characters and interesting+inventive powers keep it powering through even when it can drag on.
Looking back on it through a myriad of discussions I've had over the years, there are serious problems with the worldbuilding and setting around the story, and I've grown more and more disenfranchised with Taylor's perspective as I get older. It's such a teenager "I'm the only one right, everyone else is getting in my way, and I'm gonna make it happen my way no matter what" mindset that is then continuously reinforced by the story to the point of other characters being frustratingly stupid or incompetent. At the same time, Taylor just became an unlikable character to me at a certain point because of her constant downward trajectory of morals combined with her stubbornness and a story that kept creating scenarios to justify it rather than pushing back against it at all.
However, I recognize that Worm was a story built on being a slightly more ostensibly "grounded" superhero power fantasy, about teenagers rebelling against authority, and it works for what it's trying to accomplish for the most part, even if the execution could be improved.
Ward (the sequel to Worm) is finishing up now, and I will say that story has a lot more problems structurally than Worm, even though I think Wildbow's writing has generally improved a lot.
- How the antagonists are handled and written in Ward are very lackluster, and I think suffer for trying to live up to the scale and sensation of the inhuman threats of Worm like the Endbringers and Slaughterhouse Nine but while still just being normal parahumans, so they're written with absurd capabilities or resources but then are unclimactically written off because there's not reasonable ways to defeat them.
- The problems with everyone being incompetent outside of the protagonists also carries through, but there's no the same catharsis to it without Taylor being an overconfident teenager who takes over it all and does it better because she's so great.
- There is not a clear story thrust or throughline in Ward basically... ever. There's a much greater disconnect between arcs because there's not the same overarching plot as "Taylor is trying to be a hero > Taylor is trying to protect the city > Taylor is trying to stop the end of the world" in Worm.
- The ending also fell pretty flat for me, as there's also some storytelling decisions that seem to weigh on artificial drama by holding back information from the reader in weirdly obtuse ways, which I think could have been handled better, and without the overarching story thrust, the final conflicts don't have as much weight as they should.
So lots of negatives. However, where Ward shines for me is the cast.
The core cast in Ward is sooooo good, and they all bounce off of each other well but with a different dynamic than Undersiders. Undersiders will give you funner snark, but Breakthrough feels like people genuinely trying to help each other be better (they started off as a therapy group, after all), which combined with them being heroes made everyone feel likable and sympathetic to me even when they had their screw-ups. Wildbow has gotten way better at relationship dynamics and I just loved seeing people interact, like Antares and Swansong's dynamic.
Nowadays, I don't know that I would recommend either Worm or Ward. If you're into comic books or looking for interesting powers and teenage power fantasy, Worm can work for you. If all you're looking for is a great core cast of characters, Ward can work for you.
