TL;DR at the end
Baseball is a great sport. It's the kind of sport that can be modified to fit the capabilities of whatever type of player is playing, something humans of all shapes and sizes can enjoy. However, when comparing it to other sports on TV, in most cases, the action is severely lacking. Summer 2016's 'Battery' takes boring to a whole new level.
Our protagonist, a cocky, arrogant brat who was already good at baseball before the show begins moves into a new town and joins the baseball team. He's a dick to everyone there, even his partner and brother. People don't like him at first and go as far as whipping him but they all eventually grow to because he's good at baseball and had already created enough needless drama. They play a good school. The end.
I told you it contains spoilers right? Jeez, you shouldn't have started reading if you didn't want the whole plot explained, iiiidiot.
In all seriousness, Battery has no development whatsoever, and ends exactly where it started. Not ideal, especially for sport anime, but it has been proven to work before. In Battery's case, it does not. The only thing happening between point A and point B is a bit of baseball and drama created between Harada and friends. But that's how it's supposed to be. Boring as it is, Battery is down-to-earth unlike many other anime, and is a refreshing change needed every once and a while. While some people may disagree with me here, I think Battery was a very levelheaded show that was nice to just sit down and watch. For most people. though, it probably won't be your cup of tea.
The thing that pushed Battery into the realistic zone was this. The animation isn't very good and, actually, the art isn't either. That said, it fits the style of anime and achieves exactly what it could within it's limits. Nothing ventured, nothing gained.
Seeing as there is barely any sound in Battery anyways, I had to dig deep just to hear it play... and was it worth it? Well... not really. Though they may be pleasant to listen to, the OST, OP and ED are just there because it would be weird if they weren't. The sound affects don't help that much, contributing virtually nothing aloft the norm. The voice acting then becomes the major factor in sound, which usually backfires if you rely solely on seiyuu to get into their roles. Battery didn't have this quandary. The voice acting is great for the main characters and the protagonist's family, and while lackluster side characters drag it down quite a bit, the vocalization is still amiable.
Just like the voice actors and animation, the characters just feel like an excuse to drive the plot in a way to create as much drama as possible without straying from it's element of realism. Takumi Harada, our protagonist, is quite the querulous guy. He has an obsession towards baseball and is just a total jerk to anyone and everyone, even his own teammates, only agreeing with them when things go his way. There really is not much more to say that hasn't already been summed up.
+Realistic art style
+Decent voice acting for the main characters
-No plot or character development
-Baseball is not a good TV sport
-Art and Sound are only sufficient not good
-Main character is annoying
-Side characters are boring
-Other main characters will argue with Takumi, but he eventually wins even if he's wrong
Battery is a good anime to kick back, relax, and just enjoy. But that's not the anime most people are looking for, especially in the sports genre. Even if you DID want an anime to kick back and relax to though, there are much better choices than this. Another one bites the dust.
