Review of Goblin Slayer: Goblin's Crown
This isn't a movie so much as a bonus episode OVA. Roughly a third of the movie is just a recap of the first season of Goblin Slayer, and the rest of the movie feels less like a movie and more like an episode of the anime. The episode itself is fine, with plenty of action and a bit of suspense but it does not stand out as anything special. The extra characters that you meet in this episode don't really have anything special going for them that will make you remember them and the big villain is not as impressive, intimidating or as dangerous as oneswe've already met and defeated in season 1.
That said, it's still Goblin Slayer. If you like the show, like the characters already then this is worth a watch, but calling it a Goblin Slayer movie is setting people up to be disappointed. It's closer to an OVA, and even then it's an average one.
