kamen rider ZO executed the kamen rider series's "using the power of evil for good" idea extremely well, ZO's design is fantastic and so are the monster designs, the cast and acting is good, i liked all of the characters (though some got pushed to the side) one of the main complaints i had is that it feels like it is a continuation of something but the info the movie gives you is already enough to understand who these characters are, i do think this movie is a good starting point if you want to dive in to the kamen rider series
