First Impressions Are Everything (Except When They're Not): Ranking Anime Opening Episodes From 'Instant Classic' to 'What Did I Just Watch'
There is a very specific kind of pain that comes from sitting down to watch a highly recommended anime, pressing play on episode one, and immediately feeling your enthusiasm slowly drain out of your body like air from a sad birthday balloon. Conversely, there is no feeling quite like a pilot episode that punches you so hard in the first five minutes that you're already texting your group chat mid-opening credits.
First episodes are the handshake of the anime world. Some are firm, confident, and memorable. Some are sweaty and weird. And some leave you questioning whether the other person even knows what a handshake is. We've sorted through the chaos and built the definitive tier list of anime opening episodes — ranked by how well they actually did their one job: making you want to watch episode two.
Buckle up. We're going in.
S-Tier: Hooked From Frame One (You Cancelled Your Plans Immediately)
Attack on Titan, Episode 1 is the gold standard. You get a giant creepy face peeking over a wall, the world's most unsettling smile, and a boy who just watched his mother get eaten. All before the opening theme even plays. Nobody who watched that episode in real time walked away casually. You either immediately started episode two or you sat in stunned silence staring at your ceiling. That is a pilot episode doing its job at a PhD level.
Fullmetal Alchemist: Brotherhood also earns its spot here. Dropping viewers into a fully realized action sequence with two brothers dismantling a terrorist cell using alchemy they casually invented before puberty? Iconic. The show trusted you to keep up, and that confidence was infectious.
Demon Slayer's first episode is quieter than you'd expect, but the emotional gut-punch at the end of episode one — and the way it recontextualizes everything you just watched — is legitimately masterful storytelling. It's a slow burn that earns every second.
These are the pilots that made streaming services genuinely dangerous to your sleep schedule.
A-Tier: Strong Start, Minor Turbulence (You Were In, But You Had Questions)
Death Note opens with a lot of promise — Light picking up the notebook, the shinigami exposition, the early cat-and-mouse energy — but it takes a minute to get its footing. The first episode is good. Not 'cancel dinner' good, but definitely 'okay, one more episode' good. That's still an A-Tier performance.
Jujutsu Kaisen has a great pilot too. Yuji eating a cursed finger while his grandfather dies is a bold creative choice, and the show commits to that unhinged energy immediately. It's not quite the cinematic event that AoT episode one was, but it plants its flag firmly and clearly in the 'we are NOT playing it safe' territory.
Steins;Gate is the interesting case here — the first episode is deliberately confusing and kind of slow, but in a way that feels intentional rather than sloppy. It's like a puzzle that rewards patience. You're not hooked by action; you're hooked by the unsettling feeling that something is deeply wrong and you need to understand what. That's a specific skill, and it earns A-Tier.
B-Tier: Fine, I Guess (The 'Sure, Why Not' Zone)
This is where a lot of beloved anime actually live, and that's okay. Naruto's first episode is charming but clearly still finding its identity. The fox spirit lore is interesting, Naruto is likable, but the production quality and pacing feel like a show that hasn't realized yet how big it's about to become. You watch it and think, 'yeah, I can see why people like this.' Not exactly a ringing endorsement for episode one specifically.
One Piece suffers from a similar issue — the manga-to-anime transition in the early episodes is rough around the edges, and the pacing of the first episode asks a lot of patience from a modern viewer. The foundation is there. The execution is B-Tier at best on first impression.
Sword Art Online's pilot is competent. It sets up the stakes, the world, the mechanics. It is fine. It is perfectly, aggressively fine. Which, for a show that was supposed to be a genre-defining moment, feels like a very B-Tier energy.
C-Tier: We're Not Off to a Great Start, Pal
Some shows are victims of their own ambition. Hunter x Hunter (2011) has an opening episode that's pleasant but almost aggressively low-stakes for what eventually becomes one of the most brutal and emotionally complex shonen series ever made. If you judged HxH by episode one alone, you'd assume it was a light adventure show for kids. Which, to be fair, it kind of is — until it absolutely isn't.
Bleach spends most of its first episode doing adequate setup work that could have been condensed into about eight minutes. There's potential in Ichigo's character, but the pacing is glacial and the animation is doing the bare minimum. It's not bad. It's just... there.
D-Tier: The Fumble Heard Round the Internet
Look, we're not here to bully. But some first episodes are genuinely baffling in how poorly they sell their own show.
Early isekai entries from the mid-2010s boom deserve a collective moment of silence here. The formula became so rigid — protagonist dies via truck, wakes up in fantasy world, gets overpowered immediately, harem begins assembling — that you could practically write the first episode of a dozen different shows without watching any of them. When your pilot episode is indistinguishable from six other pilots that aired the same season, you've fumbled the assignment.
And then there are the shows where the first episode was so poorly received that the studios retroactively re-edited or re-released them. That is a very specific kind of first impression to make.
The Verdict: First Episodes Are Harder Than They Look
Here's the thing about pilot episodes — they're doing an almost impossible amount of work. They have to introduce a world, establish characters, set a tonal expectation, and convince you that twenty-plus episodes of your life are worth handing over. All in about twenty-three minutes. It is genuinely hard.
The shows that nail it tend to do so by committing completely to a feeling rather than trying to explain everything upfront. The shows that fumble tend to over-explain, under-deliver, or mistake 'confusing' for 'mysterious.'
But here's the spicy take this tier list is leaving you with: a bad first episode doesn't always mean a bad show. Some of the greatest anime ever made have rough pilots. The flip side is also true — some shows peaked at episode one and spent the rest of their run desperately trying to recreate that energy.
First impressions matter. But in anime, like in life, they're not always the whole story.
Now go check what's sitting at episode one in your backlog. You've got work to do.
