Dare I compare Professor Layton with Detective Conan? Sure, they’re both mystery-solving series but they’re actually based on different approach. Detective Conan relies more on serious crime cases to satisfy audience’s thirst for mystery while Professor Layton’s emphasis is on puzzle games and fun little adventures. Even though I said that, I can’t help but be reminded of Detective Conan’s Full Score of Fear when I finally watched Professor Layton and the Eternal Diva.
The only reason for that is music. The Detective Conan’s 12th movie revolves around stage performances with pipe organs and the Professor Layton movie had something similar. Rest be assured, they are nothing similar story-wise.
