This anime was a piece of crap
After watching the series. The most god awful thing about this series in my opinion is how they keep harping on about how "brilliant" those two opposing commanders were and the fans even commenting on how the battles were "realistic". Despite the tactics and maneuvers they were doing were beyond stupid to anyone with an elementary knowledge of physics.
Here's some examples:
1. In one battle both sides idiotically pilot their whole fleet into a hydrogen gas giant's gravity well, this was suppose to be a good tactical maneuvers even though in real life everyone knows it'll just slow all your fleet movements to a crawl. Then they were surprised someone had the "smarts" to ignite the atmosphere with a bomb.
2. In another battle, one brilliant tactic consist of moving one fleet slowly straight THROUGH the enemy fleet then slowly turning around and firing at them from their "flank". The enemy commander of course let this happen without even firing his weapons when they were in range, because somehow he was convinced "it was all a trick"!! And that he must be CAUTIOUS and WAIT to see what happens!? WTF?
3. In battles the commanders often try to "surround" the enemy as if this was some 2D land battle and not a 3D space battle. Obviously the ships in space have never thought of going "up" or "down" to escape. It doesn't help the tactical displays which the commanders use look like 2D chessboards. Or that they don't even stagger their formation to prevent friendly fire.
The "brilliant" tactics used on the show consists of silly stunts like above and not actual tactics that make sense. Like here is a big space station on the show that's suppose to be to undefeatable. But its static and noone has ever thought of accelerating an asteroid or planetoids towards it with a mass driver. If they can accelerate ships to light speed, don't they realise how much damage objects can do if they're traveling at light speed?? They don't use orbits to slingshot ships, they don't use nebulars or hiding behind planets to stage ambushes, they don't use probes to recon, or take advantage of any special effects of their weapons. Instead most battles consist of charging straight at each other in the amorphous blob formation with their standard pew pew lasers.
Its obvious very little thought into was put into the actual battles or that who ever thought of battles was an complete idiot.
If anyone wants to see what a real space opera with political elements should look like they should check out the Lost Fleet series of novels by
Jack Campbell.
