The animation is a bit crude by today's standards, but only on the surface. Its style and heart are still unique and compelling, and clearly each frame is lovingly crafted. The music is phenomenal and moving, especially given that it was probably taken from the original 1974 film. The SF ideas presented (e.g. holography room, space/time warps, etc.) are borrowed by many films and series that have followed. The plots, though overly dramatic sometimes, are poignant and epic nonetheless. Overall, the series is rough on the edges, with many minor flaws such as character inconsistencies and scientific factual blunders, not to mention the gross inefficiency of using a seagoing battleship design for a space cruiser. However, the core of it is pure genius and I'm held in rapt admiration of it.
The references to World War II are obvious: fighting an almost hopeless war against an evil, corrupt empire. The enemy leader, Desslok, even looks like a Nazi with the uniform he wears. The story is emotionally driven: fraught with patriotism, sacrifice, and the desperation to save Earth. The writers employ healthy doses of characterization and detail, something sadly lacking in most other series. Lots of morality and spiritualism are brandished effectively such as (paraphrased) "don't destroy other worlds in desperation, even though Earth will die in less than a year", "with great power comes great responsibility", "take pains not to harm indigenous life on other worlds", "take the blame for your actions and move on", "in spite of all the Capt has lost, he goes on, indomitable", and "your brother survives in you."
Part of the series' attraction is the epic space battles. The see the animators craft the ships and their weaponry, and put them into action, is a sight to behold. "Space planes" soar in formation around the enemy and bristle with missiles and torpedoes. Weapons of mass destruction are brought into play to save the day. And the battleship Argo itself is such a work of art. Its splendor is shown off in a vast array of combat attitudes. They couldn't resist having the ship land in on an ocean, so that its seagoing superstructure and profile could be admired (powerfully reminiscent of the sea battles in our history). Overall, the heroic spirit personified by ship and her crew is exploited to the hilt, and it's hard to resist cheering for them in spite of the melodrama.
