Now to show why I consider Black Lagoon top anime.

In the South East Asian town of Roanapur is a lawless zone where any world renowned criminal group resides, free from international laws, the many mafias, cartels, triads and yakuza all look to a group of pirate mercenaries for smuggling called the Lagoon company led by Dutch who along with crazed gunslinger Revy and hacker/mechanic Benny acquire a salaryman from a botched negotiation, pretty much abandoned by his employer the Salaryman takes the name Rock and becomes Lagoon's negotiator and professional, with no shortage of jobs on offer and as much action as swear words, welcome to the jungle, we got fun and games.
So why do I consider this the best anime of all time? Because it perfectly encapsulates the entire anime experience.
Think about when you first saw anime, and I mean a real anime; for me, anime when I first discovered it felt like a different world, there was more violence, there was swearing, the women actually kicked ass, it was funny, it looked amazing, it felt like the next stage up from cartoons.
Everything that Black Lagoon does matches all those feelings in spades.
It's setting provides a violent paradise where any amount of gun play and fighting is common, send in Roberta and that goes up to 11.
It's dub is perfect mainly because they do speak English in universe, and it wouldn't nearly be as good without Maryke Hendrikse's portrayal of Revy.
All the women are terrifying and it kicks ass.
It even has omake to lighten the mood.
The story is pretty much told through an audience surrogate in Rock which keeps the chaos in check.
It's just built to perfection, there's a lot to enjoy so go watch it.
Final Verdict: It will take something monumentally special to kick Black Lagoon off my number 1 spot.
