Smith’s character gives the story an emotional weight and Reynolds delivers an endearing comedic performance that’s closer to his subversive Deadpool schtick than you’d expect. While video game movies haven’t had the best track record, this movie is by and far the best example of how to do one right.

Detective Pikachu slogs, and its joys are fleeting, like a battle with a wild Mewtwo that you just can’t seem to catch.

Without Reynolds this would be pretty run-of-the-mill; with him it’s a perfectly acceptable family movie. Given the history, that’s a giant leap for Pokémon-kind.

It turns out Pokemon Detective Pikachu isn’t half bad.

Reynolds and Pikachu make an inspired combo in a CGI/live-action mash-up that otherwise adheres to a rigidly boilerplate formula.

As the wisecracking voice of Pikachu, Ryan Reynolds deserves some sort of special citation for doing the best he can without Deadpool’s f-bombs (or a decent script) to lean on. But the main problem is that the film’s gumball-mayhem plot is so frenetic that it’s impossible to determine if it makes a lick of sense. Maybe that was the point.

It seems that this particular game of Pokémon needed more time at the gym. Yes, that’s a “Pokémon Go” reference, and if you can’t follow it, don’t bother.

Beneath the predictable story, Detective Pikachu isn’t about much, and if you need Wikipedia to explain who Mewtwo is, most of the jokes will go right over your head. The whole thing is a bit too childish for adults, and a bit too convoluted for kids. It absolutely deserves an Oscar nomination for Best Visual Effects however, even if the subject matter makes me think it’s unlikely to receive one.

If you have waited your entire life to see this world brought to life, and to watch humans and Pokémon occupy the same space, then Detective Pikachu may well be everything you ever wanted. But for those of us who don’t know a Jigglypuff from a Charizard, this film scores low on wit, coherence and engagement.

Though consistent with the game (with a few extra but obvious twists thrown in for good measure), the story of “Detective Pikachu” doesn’t allow nearly enough Pokémon-related action, while the quality of the computer animation (by Moving Picture Co. and Framestore) falls far short of the basic level of competency audiences have come to expect from effects movies.
