I don't even recall how I first heard of Black Lagoon. Having watched the series on YouTube, I was hooked from the first episode. The animation is stunning, especially the beautiful shots of the South China sea. This disk contains one of my favorite parts of the series, from the beginning of episode one, where we meet Rock and see the life he escapes from, to the beginning of episode three, when we first see Rock "on the job" and attempting to reason with the freight ship until Revi uses an RPG in her own particular method of persuasion.
Black Lagoon teases us with a world so close to our own that we are never quite certain if we are dealing in supposed reality or not. Though the city of Roanapur doesn't really exist, it very easily could under another name, it seems, and the geographic locations are mostly accurate. Back stories set in real history (such as the Soviet invasion of Afghanistan) provide a realistic setting for some of the characters as well. Weapons depictions are also almost startlingly accurate.
On the other hand, the use of those weapons and the capabilities of the characters often reminds us that we are indeed watching an anime, with various characters (mostly female) who are able to wield their choice of weapons with nearly supernatural finesse and ability.
It's all in good fun, and the series isn't afraid to poke fun at itself, while sometimes thoughtfully raising questions of moral perspective.
There is some mature content, which while often unnecessary is also part of the criminal underworld backdrop that is reinforced throughout the series.
These are not nice people, they live by violence and crime. Yet still we develop an unshakeable attachment to them: The capable and dangerous Balalaika; the murderous, hot-headed, yet somehow endearing Revi; the reluctant but ultimately courageous Rock; and many other characters, developed to varying extents but all interesting.
I look forward to the rest of the episodes being released.
Like everything else, this series has its flaws, but is intense, compelling, and ultimately satisfying.
