Man, revisiting the manga after watching the anime a bunch of times was eye-opening. The pacing is totally different; the first half flies by, but the second half after a certain character's exit... it drags. There's way more of the investigation team just sitting around talking in circles, which I guess is more realistic but less thrilling. The ending sequence is completely restructured too. The manga leans heavier into the psychological dread and the logistics of the notebook rules, while the anime amps up the cat-and-mouse tension visually and with that iconic soundtrack. Some of the Yotsuba Group stuff feels more fleshed out on the page, but honestly, I miss the anime's cleaner, more dramatic finale.
For me, the biggest difference is in Light's portrayal. The manga gives him more internal monologue, more of those petty, arrogant thoughts that get smoothed over in the adaptation. You see him genuinely sweat and panic at points where the anime keeps him cool. It makes his descent more grotesque and less... stylishly villainous. Mello and Near get more panel time to breathe, but it still doesn't quite salvage that arc's pacing issues for me. The anime's condensation works better there, even if it cuts some neat strategic details.
