I actually love this discussion, because it's exactly how you're supposed to feel— the manga itself is even making fun of us for it, with characters noting how everything feels dreamlike and anticlimactic.
CSM is currently acting as a meta-critique of shonen battle-manga stories, fights are either totally one-sided or skipped, no training arcs, Denji is punished for and now refuses to become Chainsaw Man, the shonen protagonist of Chainsaw Man. The main driving force of the plot is currently a woman (not new for CSM), specifically the female protagonist that other characters (Katana, President-kun) simply file into the role of "Chainsaw Man's woman".
Very excited for what Fujimoto is cooking, the apocalypse is 5 months away.
