The problem of the anime industry lies within the otaku who likes terribleness and puts down greatness. It should be obvious how KLK is terrible, along with almost... Any other battle shonen?
Then they get praise despite the fan service in them. However, they'll lolicons whenever they hate on something, although fan service. This fandom should be bombed and recreated proper. One guy simply didn't take me seriously because I disliked four anime (Naruto, DBZ, One Piece and KLK) and thought that if I just disliked two that would make him take me seriously. In other words, I'm only allowed to dislike two. Disliking more means my opinion is garbage.
Your opinion is only garbage if you dislike Patlabor and Legend of the Galactic Heroes.
(Patlabor being one of the most realistic mecha anime ever devised yet utilizes satire and comedy effectively to keep itself entertaining, while the movies take a bit of a darker approach yet still find a way to be suspenseful and have immersive settings.)
Legend of the Galactic Heroes was originally a sci-fi novel series written by Yoshiki Tanaka, and an OVA series was made based upon the novel, and used a mostly public domain soundtrack of classical music, which strangely fits in with all of the epic space battles, political conflicts, backstabbing, and axe fights that go on in this anime. The story is the most in-depth and complex thing you will ever see in anime, and it's executed almost flawlessly. It's a bit slow-paced, but if you don't mind that, there's so much to this anime.)
As for fan-service in anime, well, it's been there for a long time. Anime from the '80s had fan-service, but it also had other things to keep it entertaining. Whether downright bizarre animation, interesting stories, bizarre stories, and excellent characterization, and even mechanical designs. The big problem with fan-service is that it's sometimes used to cover up plots that lack substance or to cover up poor characterization. It shouldn't be the selling point of an anime, but rather the icing on the cake, depending on what the demographic is and what sort of style and feel it's going for.
Some of my favorite OVA series, which are Gunbuster and Bubblegum Crisis, are not without fan-service, though it's not too jarring or out-of-place. (OVA 2 of Gunbuster can feel a bit awkward at times, though, but it's still not out-of-place.)
Eh, thing is, battle shounen demographic-wise is typically for viewers in their pre-teens to their mid teens. People watch these for well-animated battle sequences and ridiculous, outlandish, cheesy plots.
[I mean, just watch the original Saint Seiya, or even watch the original Hokuto no Ken. The plots sometimes seem like they're pulling stuff out of their asses, but it tends to border on "so bad it's good".]
Some people even watch shoujo-genre magical girl anime for the same reason. [Nanoha will always be my favorite magical girl anime series. ¬_¬ Yes, I intend to watch the Sailor Moon remake, but I need to finish the 5th season of the original first. >_< Which I'll eventually get around to.]
You want something with a more purposeful story? Watch the older Gundam series, or, heck, watch Votoms. Or watch the aforementioned Legend of the Galactic Heroes. [LoGH is so packed with story and characters that it can be a bit difficult to digest, though. Trust me, though, it's good.]
