I'm not going to rate the show by different categories, as I tried that and it sounded boring, but I did find it more enjoyable seemingly than many other reviewers here did, and wanted to express that.
It doesn't stand out too much in any area, and I doubt it will join anyone's list of favorite anime, but I've found it surprisingly entertaining and a fun watch so far at episode 11. I enjoy many of the characters, the arcs that some of them have had, and the actual climbing parts are very engaging to me, despite my complete lack of background in or knowledge or the sport. Although the climbing is not shown with too much detail I imagine compared to the real sport (I don't feel like I've gained a whole lot of knowledge while watching or anything), the characters' motivations and stories help make it entertaining.
Also in case the poster art made you think of avoiding it because it would have heavy fanservice, fear not. I actually don't think the fanservice is very heavy at all - despite some angles while climbing seeming a bit that way, the show itself seems quite intent on depicting the characters' stories seriously and not undermine that with leering camera angles the majority of the time.
One moment that made me a bit uncomfortable and wish it hadn't been included was *SPOILERS* one of the characters - who is played as a bit creepy, but in a funny way - punishing a climber who tried to sabotage a promising newbie. She creeps up behind her and scares her by not letting her collar go (and also being creepy is kind of her gimmick, but usually in a pretty harmless way), then when the girl insults her, she says "Come with me to the dressing rooms... I'll give you a good dressing down there." She then drags the scared girl away with her while creepy music plays, while the girl screams things like "Spare me!" This is the most uncomfortable moment in the show in my opinion, (with the exception of one more moment I will mention next), so unless you're very sensitive to this type of "joke", it's quite easy to look past in my opinion. It's just a shame, as if they'd just left out the threat of being forcibly undressed, it would've just been a funny scene where someone got payback for trying to sabotage a fellow climber, but as it is, it's a small blemish on the show in my opinion.
The other uncomfortable moment in my opinion was *SPOILERS* when a character is called "chubby" with no visible chubbiness to speak of. This happened in the middle of a training episode, and while the character definitely needed extra muscle to be able to compete, she never appeared even close to "chubby". To add insult to injury, I can't even tell a difference between her weight before and after she gets stronger, so not only is it worrying seeing a visibly quite thin girl being told she's "chubby", her body when fit is drawn the exact same anyway, indicating it looks plenty thin enough to be fit for competition before. This is another part that I just have to sigh and ignore, as it is only a few times in the episode it's mentioned, and weight issues, from memory, are never mentioned again outside this episode, so it's quite easy to pretend this is her teammates positively encouraging her to gain muscle and increase her fitness, rather than making someone think they're overweight when they're perfectly thin already.
Overall, I don't think you should enter this show expecting to love it, as I don't think its appeal is that broad or strong, but I started it just wanting a simple show about a niche sport, and I came to really like it. To me, it's one of those shows you don't really include with your favorites, but because they were such a pleasant surprise, you become a bit of a special series anyway, and I hope this might encourage others to give it a go and maybe come to like it as well.
