From reading the LN's I can say that, Goblin Slayer has pretty interesting world building and lore. Like how none of the characters has actual names. Or the whole goblin slyer thing is kind of a background plot of the Hero's story. It has decent character work and pretty good actions. But unfortunately none of these can be found in this lackluster season.
This was in no way a bad season but just a very boring one. The plot didn't seem to advance much. And the few interesting storylines like the one about new recruits didn't quite land well.
For the positives I can say that the opening and soundtracks were great. Also this season expanded the world building a bit (But not nearly enough!). If you enjoyed season 1 you probably going to like this one as well.
