Bokurano has a story that doesn't really make much sense with its "rules of play" until about half a dozen episodes into the anime. From there it finally opened more of the purpose behind the giant robots and why the battles in them must be won at all costs. The first three quarters of the anime are full on action intense. However as the government and researchers become more aware of the situation, it slows with the action, takes longer to get through the explanations and reasoning behind a persons motives.
Art styles are fairly disappointing for something made in 2007. Whether this is because of a low art budget or not, is unknown. Characters and non scenery items are very basically drawn and mouth movements could not have been done a lazier way. A few scenes depicting horror or large amounts of gore, are drawn extraordinarily well. However the 3D CG used in the robots is fairly well done and very smooth with its animation. It almost makes you question if this is where their entire art budget went.
Major battle sequences, emotional character scenes and introductions to the current scene. They all seem to have their own music piece that is used throughout the anime. It's most times very soft compared to the voices and can sometimes no unnoticed. A few new music pieces pop up in the final couple of episodes but nothing too interesting. many generic stock sounds are used throughout and the few that sound unique, especially during the robot battle scenes, are recycled more times than you can count.
Characters were sometimes bland and didn't get hype at all which can be disappointing but the character development for most is short and doesn't drag down on the mass amounts of action. Others drag on for far too long and can waste an entire episode filling in what can be explained in five minutes. This can occasionally kill the mood as it gets to starting action scenes, making you hype then drags on about a characters back story for over an episode.
Despite these slow points dotted throughout the anime, it really is quite enjoyable for the first 18 episodes and the finale. The 5 episode gap between them makes you want to curl up and sleep through it, it waffles on that long. It does have a fitting ending battle, but it just doesn't quite make up for the mass stalling in the few episodes prior. A few times in the first half of the anime you question just how messed up they made this anime as well as a couple scenes that make you question how they got away with just the "Violence and Profanity" tags.
