# INTRODUCTION
Nanatsu no Taizai is a shonen fantasy that starts with a simple yet interesting idea, backed by a decent initial pace and a cast that had the potential to be charismatic. However, what begins as an enjoyable adventure quickly turns into a sequence of forced plot twists, random power-ups, and increasingly questionable narrative choices. Reading this manga felt like getting on a rollercoaster: the initial climb is solid, but the drop is so steep the whole cart flies off the rails.

#PLOT AND PACING The story begins with Elizabeth searching for the Seven Deadly Sins to save the kingdom of Liones. The first narrative arcs are simple but effective, following a “recruitment → mission” structure that, while nothing groundbreaking, works just fine. The plot flows smoothly, without aiming too high, but keeps a decent balance between action, mystery, (questionable) comedy, and worldbuilding.
The problem starts once the story gets past its first big clash with the initial antagonist. From that point on, it begins to pile up new enemies, subplots, and plot twists that feel completely improvised.
More enemies mean more challenges, more challenges mean more difficulty, and more difficulty, in this manga, means random power-ups. Take Meliodas, for example: his powers were initially sealed because they were too unstable—or rather, because the plot demanded it, since otherwise he would’ve steamrolled the early villains. Unsurprisingly, he gets those powers back the moment stronger enemies show up, and from there the series falls into a constant cycle of “the real enemy was someone else,” resurrections, power-ups, and retcons.
The Demon King (or whatever his name was—I honestly don’t remember), the main antagonist of the final stretch, comes back several times in different forms, but never manages to generate any real tension. The only remotely interesting subplot is the one exploring Meliodas and Elizabeth’s past, which brings a bit of emotional depth to an ocean of repetitive battles. The climax lacks impact, and what should’ve been an epic ending turns out flat, predictable, and comically cliché.
#CHARACTER The cast is large, but very few characters actually leave a mark. Ban and King start off well, but their potential gets wasted by some pretty questionable narrative choices. The only truly charismatic character is Escanor—his personal arc stands out for its originality and sheer presence, and (SPOILER) he’s also one of the few who actually dies for real in all the story. The other Sins, unfortunately, remain flat or get lost in excessive fanservice and over-the-top power-ups. 
#ART STYLE Suzuki’s art style, especially in the early chapters, is quite pleasant, with recognizable characters and a good sense of dynamism. Action scenes are clear and well-paced, particularly in the first volumes. Unfortunately, this aspect also starts to decline: the detail in non-action scenes becomes simplified, certain designs are reused, and the overall quality loses its edge compared to the beginning.
Now, I’m not saying the art is generally bad—it’s not. It’s just that as the story goes on, the quality becomes inconsistent in many scenes.
The paneling and scene direction remain among the few solid elements of the series, as does the general readability. However, the constant abuse of flashbacks—sometimes several in the same chapter—makes the narrative feel messy and constantly breaks the pacing. 
This is a small example to show how good he can be if he puts his mind to it
#CONCLUSION Nanatsu no Taizai is the perfect example of how a strong start isn’t enough to save a story from itself. The main issue isn’t the use of clichés—it’s how lazily and repetitively they’re handled. When every character can come back to life, every battle loses its weight. When every reveal is contradicted in the following chapter, any emotional investment just vanishes.
The repetitiveness in the second half becomes almost unbearable, and the complete lack of real consequences kills any sense of tension. What’s left is a manga that drags itself to the end with the inertia of something that’s already said everything… but keeps on talking anyway.
One of the biggest problems lies in the handling of the power system, and in the constant confusion caused by characters who seem dead but, more often than not, come back a few chapters later.
I’d only recommend this series to newcomers to the medium, or to someone looking for something visually flashy without much narrative depth. If you’re after consistency, tension, and solid writing… you’re better off looking elsewhere.
