Not every great anime opening theme is attached to an equally stellar anime. In fact, there are plenty of anime openings that are better than the anime they introduce. If you find yourself bopping along to a great jam long after you've forgotten the premise of the anime – or tried to expel it from your memories – you have encountered one of these songs.
Some awesome opening credit numbers – often referred to as OPs – are paired with anime that's good, but not as fulfilling as the song alone. Others, like the Sousei no Aquarion OP, are great songs attached to anime that fails to make a good impression.
While it's disappointing when an anime isn't as good as the theme song implies, at least you get a nice song out of the experience.
It's nearly impossible to listen to "Bomb a Head V" by m.c.AT featuring DA PUMP and not get, well, pumped. The same can't be said for Tenjou Tenge, a 2004 anime about students at a martial arts school.
It's a fanservice-heavy shonen battle anime with little character development and a lot of time wasted on poorly-placed flashbacks that add almost nothing to the story. It's not terrible, but the theme song is a heck of a lot better.
"Sousei no Aquarion" is probably the most notorious example of a lackluster anime with a spectacular theme song. AKINO's "Genesis of Aquarion" features soaring vocals, lovely instrumentals, and is overall a joy to the ears.
Unfortunately, the show is also a mediocre mecha anime that feels dated in 2018, but wasn't particularly interesting when it came out in 2005.
Love & Lies was widely regarded as one of the worst shows of the 2017 summer season. Set in a universe where marriages are assigned via scientific algorithm, the anime follows a teenage boy named Yukari Nejima who falls in love with someone other than his assigned bride.
It's an intriguing premise, but the series totally fails to capitalize on it. This is majorly disappointing, because not only is the idea behind the anime a potentially good one, the opening theme, "Kanashii Ureshii," is top notch.
One of the coolest things about anime is that theme songs are often performed by actual musicians with non-anime discographies. While well-known bands tend to lend their talents to high-quality anime, they might also do so for anime that are just kind of okay. This is what happened when OLDCOLDEX did the opening song for Servamp.
Servamp is a totally adequate anime about vampires who form servant-like partnerships with humans, but "Deal With" is a hard rock masterpiece.
