For most TV shows, the opening is a skippable formality. For anime fans, it's a 90-second art form. A great anime opening, or "OP," does more than just play a catchy song over a cast roll call; it sets the tone, tells a story, and is packed with symbolism and foreshadowing. It's an essential part of the viewing experience, but what exactly separates a good OP from a truly legendary one?
Visual Storytelling and Tone Setting
The most important job of an OP is to establish the show's identity. The first opening of Attack on Titan, "Guren no Yumiya," is a masterclass in this. From the very first second, the German narration, epic choir, and frantic, militaristic visuals tell you everything you need to know: this is a desperate, brutal war for humanity's survival. In contrast, the opening for Kaguya-sama: Love Is War, "Daddy! Daddy! Do!," is a stylish and jazzy sequence that perfectly captures the show's blend of romantic mind games and chic comedy. A great OP is a perfect thematic appetizer.

Symbolism and Foreshadowing
The best OPs are layered with meaning, rewarding attentive fans who re-watch them week after week. They often contain subtle visual metaphors and foreshadow future plot points. The iconic opening of Neon Genesis Evangelion, "A Cruel Angel's Thesis," is packed with religious and psychological imagery that hints at the series' deeper, complex themes long before they are revealed in the plot. Similarly, many JoJo's Bizarre Adventure openings are famous for evolving over time, with new sound effects or visual changes appearing after a key event happens in the story.

Musical and Visual Synergy
Finally, a legendary OP has perfect synergy between its music and its visuals. It's not just about having a great song; it's about how the animation is cut and choreographed to the rhythm and emotional beats of that song. A perfect example is the first opening of Jujutsu Kaisen, "Kaikai Kitan." Every punch, every character introduction, and every transition is perfectly timed to the song's beat, creating a sequence that is not just visually exciting but also incredibly satisfying to watch. The visuals don't just accompany the music; they dance with it.
A great anime opening is a short film in its own right. It's a promise to the viewer about the story to come, and when done right, it becomes just as iconic and beloved as the show itself. So next time you're tempted to hit "Skip Intro," maybe give it a watch—you might discover a whole new layer to the story.
