Matt Berry is best known as Laszlo Cravensworth, the flamboyant vampire in the FX comedy What We Do in the Shadows, which premiered in 2019. His exaggerated Received Pronunciation and theatrical line readings made Laszlo a fan favorite and a steady source of reaction clips. Short utterances like good idea circulate on soundboards and in edits because they carry his full comic persona in seconds. Editors favor it for dry, knowing approval, a very British way of saying yes that feels funnier than a plain agreement.
