This review has the inclusion of the OVA which is more of just a 13th episode.
Very rarely are ports from games into shows or movies done well and this is no exception. Or at least for the most part. For those that haven't played the game, its a decent anime with a few things in it that you would not see in any other anime. Such as a robot drag Queen for instance. However for those that played the games first. This anime can be rated fairly low in comparison.
With a story line of a few key villains that add up to a final stand, Neptunia the Animation seems to have played itself rather well despite its large tangent from the games. With even the fan service episodes having major key points, it really does make a serious habit of making a fool out of itself but seems to make up for itself in a few a scenes that can tag at ones feels even slightly.
Art when matched with the game, falls into place almost exactly, 3D game models aside. But when pitched on its own in the anime world, it's extremely bright and cheerful for the most part and only gets dark and gloomy when a situation goes really bad, which most time leads to easily predictable scenes if a sudden twist isn't added.
Music is the disappointing factor, with only a few songs, including the opening and ending, used many times throughout its short lived season. Although despite these are well made, the constant use gets a little boring. The few original pieces that are played are so dulled out into the background its hard to appreciate them without loosing out on what happening in the anime. Sounds are however this sections redeeming factor as the sheer amount of unique sounds for each and every object is not something that often seen in a short anime.
Character development outside of Peashy's character, is the one part both new watchers and players of the game, can agree in saying there is almost no character development as it opens, plays and ends with them all on the same terms with one another with only minute wavers to each others relations during the anime.
Overall enjoyment was quite lacking as while it had a few suspenseful moments, they were all short lived while the rest of the anime left nothing to be desired. The few scenes that poke at your feels can seem redeeming but they just get ruined again in the next episode with the animes own way of ruining its own lead up. The one part that can be heart crushing is the first scene of the OVA to those that played the games. The game players will know the OVA all too well. While everyone else is left wondering what the hell the story line is doing.
