From the concept alone, you already know if you'll enjoy Detective Pikachu. Those who don't even know what a Pikachu is need not apply. But, if the idea of Ryan Reynolds voicing the second-most iconic cartoon mouse of all time (with a little hat on!) amuses you, then amused you shall be. Even with its basic plot and forgettable side characters, Detective Pikachu succeeds on the strength of its two leads and a direct tap into your childhood nostalgia for all things Pokemon. And did I mention the Pikachu has a little hat on? It's just wonderful.
