¿Qué tiene de malo intentar ligar en una mazmorra?

Going by the name and a lot of the early interactions within this series you would think this was just a dungeon exploration anime with plenty of over the top breasts and a whole host of girls in love with an adorably clueless and well meaning adventurer.

But the latter does subside and the side characters are actually interesting rather than just pointless harem bimbos.

The plot becomes way more complex and interesting and the world building is actually quite expansive.

My biggest issue really (having watched seasons 1 - 4 and the film) is the level of plot armour that is going on. Is completely removes any sense of threat because you pretty much know who is going to survive all the time.

Given how people are ripped to shredds, limbs and body parts can go flying, etc, I would have expected this anime to be more willing to remove the plot armour on occasion and if it did then I would certainly give it a higher rating.
