And to make a good objective opinion, the second season of Koreha zombie desuka is the worst shit to come out of the tv industry right after walking dead season two.
I hate season two of TWD ... they made Shane into a psycho and killed
him because
PLOT, spend half of the screen-time about Lorry and her "feelings", and reduced the cast IQ to the level of Gerbils.
I couldn't wait for Lori to die in Season 3 and Karl to be lost in the woods, but I gave up on the franchise itself entirely, not longer interested.
But back on topic, Korewa Zombie Desuka 2 is was bad.
Fanservice is a two-edged blade, Ikkitousen or HotD are supposed to be like they are, full of it and so overly done it's fucking hilarious and makes for great laughs.
It is great when it is part of the whole concept and well done, that is for sure. Especially if the other elements of the anime are also compelling and the characters are memorable. Having brought Samurai Girls earlier one reason I like it is also because somehow the great hope of Japan Yagu Jiubei spends 95% of her time with the IQ of an adorable Gerbil and somehow transforms into a fearsome warrior with witty lines when kissed.
Making the anime absurd up to 11 can make it fun, if done right.
Then we have the Neon Genesis Evangelion like fanservice that is there just to make for fantasies of the main female cast. It's just about as important as a sex scene in a Van Damme movie.
Do I think they make the movie/series worse? No.
Do I feel uncomfortable/annoyed/leave the room/change the channel/skip forward? Yes.
The uncomfortable
"who has the remote to change the channel" moment, I feel your pain and it is not good no matter the media genre. I used to avoid watching TV with my parents when I visited them to avoid those moments.
The shift of focus in Evangelion is even more obvious with the introduction of Mari, for the sole reason of selling miniatures and printed pillows.
I do like her has a character in the third movie because of her banter with Asuka, which beats the laconic nature of Rei and the retardation of Shinji, but her main role in the cast is about appealing to the male audience instincts.
Edit:
I just realized that I like the fanservice bait of Evangelion, with a screen time of a few minutes, more than 3/4 of the main cast. I hate Evangelion, it takes my love for the universe and throw it in the bin with dumb characters.

The question then remains, will the show end up getting more viewers due to having said fanservice than the fanservice alienates? If the answer is yes, they will do it.
As long as the audience for anime is the japanese male ranging from 10-30 years of age who have never seen a woman naked it will remain the way it is now.
We can (NOT) Escape.
