What I Liked: Animation's bright and sunny and fits the mood of the series. Character designs and animation are fluid and fit the genre. Even though repeated footage was used, it didn't detract from the flow of the story. Good use of parallel storytelling in two parts.
What I Didn't: Characterisation was a massive let-down - the protagonists' actions seemed illogical and immature. Every other character aside from the protagonists were depicted in a negative and generalising light (all men are pigs; all women are harlots).
Final Verdict: Animation was good, but the writing and characterization really let this OVA down. Sure, it was linear and employed parallel storytelling, but when the characters in your character-driven story start to sound more believable if they were transplanted to a middle school (instead of being independent young adults), you've got a huge problem.
Still it was cute, saccharine and probably better suited to people less cynical than I.
