Story: 7/10
The story or overall plot progression of Hidden Dungeon is pretty standard. You have your very typical character introduction (via narration), some opening arcs to set the scene and introduce the main girls, a few growth arcs, some fillers, and finally the ultimate battle at the end. If you're looking for some philosophical deep-take, you probably will be disappointed; but if you're just looking for a good time, then it's about perfect. The pacing is decent, the arcs have pretty solid lead-ins, and you end the show with a good understanding of the characters and world.
My only issue in this regard would be the pretty underwhelming exploration of the premise: The MC can create any skill. If the show took itself a little more seriously and expanded on this idea more, it could be a lot bigger and better.
Tl;dr - Plot is standard, not bad not good.
Character: 9/10
By far the character writing is what saved the show from becoming an even worse version of DanMachi. While the harem girls aren't necessarily unique or memorable, their character designs and initiative sets them just a bit apart from the typical, ultimately making them much more enjoyable to watch; and I think this is in part due to the show knowing itself.
Unlike with a typical harem cast where the girls are passive, these girls take the initiative and work towards their harem. Some examples of this includes kissing the MC in Episode 1 (yes, you read correctly), accepting that the MC has a weird lecherous quirk instead of trying to bash his head in every 5 seconds without even listening to reason, being powerful in their own right, not waiting for the MC to be their white knight, speaking their mind about their interest for the MC and acknowledging each other as rivals without excessive jealousy, etc. All of these and more make these girls much more interesting to watch, and enhances rather than detract from the show.
Tl;dr - The girls aren't annoying and actually show proper affection to their target MC
Art/Animation: 7/10
The art and animation is slightly substandard for a typical harem adventure. This is most obvious in terms of the intricacy of skill effects and such. Other than that, it holds up well in terms of attention to detail, continuity, and style. Doesn't detract from or add to the show.
Rewatchability: 7/10
Ultimately, I have to say I enjoyed the show. I wouldn't go out of my way to rewatch it, but I might just pick it up again if I happen to remember. It gave me some good laughs, and doesn't try to fool its viewers or pretend to be a grander show. Sometimes, that's all you can ask for, as long as you don't go in expecting too much.
