I grew up with the Pokemon games and mostly enjoyed it. Ryan Reynolds delivers a few reasonable chuckles and the ultra-detailed renders of the pokemon felt pretty faithful.
I did not like the twist with the main antagonist. It felt like something out of a bad fanfiction and wasn't executed much better.
Also, there is one glaring inconsistency with the game mechanics. Without spoiling anything, at one point a Psychic type attack is used to repel a horde of Dark type pokemon. DARK TYPES ARE IMMUNE TO PSYCHIC ATTACKS. I wish that scene coulda been resolved differently...
Excuse me. I'll show myself out now.
