Can't take the Curse of Strahd seriously

Me and my friends are playing The Curse of Strahd, but we're just like a special EP of Konosuba, We can't take any of the NPCs or the lore seriously. I'm not complaining, this might be the best campaign I've ever played, and the DM said He's having a lot of fun as well, I just think it's funny when someone says "The curse of Strahd is a really serious/dark adventure" bc I aways remember my friends interactions and start laughting
