Review of Goblin Slayer: Goblin's Crown
It's a whole lot of meh, the first 25 minutes or so is a recap and the actual new content is an hour long. I'm currently at this point in the manga and it looks cool, it's paced very well and it makes sense. This movie doesn't look all that great: there's even more 3d model goblin slayer and the animation for everything is very weak. The pacing is way too fast so you don't really see any character moments (for the main cast) and obviously there's no character progression since it's a movie but considering that the story is in the mainline manga youwould've thought it'd just be in season 2 or something.
I really like Goblin Slayer but you can just skip this, chief. Honestly, the manga is probably the best way to experience Goblin Slayer.
TD;LR: Give this a miss, pick up the book.
