The plots are often rich and encompass an impressively wide variety of themes from personal and emotional struggles to major, often Armageddon-level threats and dilemmas. The darker, more confronting shows out there have often leaned heavily into harder, more mature themes and ideas to put forward suspenseful, often scary, and thought-provoking tales and character arcs. Such shows often mix in complex character development with a strategic array of eyebrow-raising plot twists and intrigue in order to make it next to impossible to guess what might happen next. That unpredictability factor is a key ingredient in creating a consistently intense, gripping viewing experience. The following shows mastered that art, hooking viewers with their fast-paced, imaginative narratives and characterizations.

From there, viewers are treated to a tough look at Izumi's determination to maintain his humanity as the parasitic invasion takes hold. Forced to uncomfortably co-exist with the monster living inside of him, Izumi's journey is a tense, uncomfortable nightmare. The anime further heats up as themes of identity, co-existence, and survival bubble up to the surface. With a rapid fire plot, thought-provoking moral and philosophical questions, and suitably violent action sequences, Parasyte pulls no punches in showing the brutality of both human and alien violence.

On top of the expected action that this premise promises, the series' real thrills stem from the often deeply personal nature of the show's look at the pilots' psychological states. Constantly faced with potential death and a sense of existential dread, the mecha pilots' hellish cracks at saving the world are unrelentingly heavy to watch. Chock-full of philosophical questioning, cryptic symbolism, and a harsh deconstruction of mecha tropes, the series frequently challenged viewer's expectations whilst keeping them on the edge of their seat. The impressive blend of high-stakes battles, major plot twists, and an atmospheric soundtrack further added to the series' suffocating level of tension.

This much-loved anime boasts a unique premise ripe for high-stakes mind games. The narrative revolves around a powerful notebook that allows him to eliminate anyone whose name he writes into it.

Light Yagami, the increasingly maddened lead character, gradually descends from a regular high schooler to a self-proclaimed god, running roughshod as detectives gradually close in. The already dark, suspenseful series is bolstered on the intensity front by its moral ambiguity, which often manages to push viewers into questioning their own ethical values. Yagami's lengthy cat-and-mouse game with the enigmatic L, a quick-witted investigator tasked with catching him out, cranks up the overall anxiety of the series even further. With its thought-provoking, often nihilistic plot and fearsome character arcs, Death Note set itself apart as a masterclass in building tension in the anime medium during its '06-'07 run.

What little is left of Earth's population now live within massive, towering walls designed to guard them from the fearsome, man-eating giants. The utterly brutal battles between the predatory Titans and outmatched human soldiers, coupled with the general, constant fear and tension of human bases being overrun, creates a palpable sense of intensity throughout the series. Better still, Attack on Titan's commendable array of moral dilemmas, complex characters, and intriguing emphasis on power dynamics adds depth and dramatic potency to the show's already emotionally charged, thrilling viewing experience.
