Videogame movies are always interesting to see. Especially the bad ones. Adaptation is a harder game than it looks from the outset: storytelling conventions, expectations, tropes, archetypes, pacing, and length all differ greatly between mediums, and that's not even getting into the factors relating to stripping interactivity from a work whose engagement relies on that interactivity. I open with this to remind people that Detective Pikachu is first and foremost a videogame adaptation, and a pretty solid one at that.
