My favorite animes:
Trigun
Trigun is a story of an unfortunate man, a peacemaker who only has a reputation for igniting conflicts - Wash the Stampede. The setting looks like it was taken out of some Wild West cowboy movie, with a hint of sci-fi tech. And I am not going to spoil anything here, so there is only one thing left to say: Trigun has quite an uneven plot. The beginning is mostly filler episodes, and it might look boring, but bear with it - you're not regretting it.
Cowboy Bebop
Cowboy Bebob is a ballade of vagabonds, a travelers without homes or loved ones. A tale about four uneasy souls, each in pursuit of their own goals. They just happened to end up at the same time, at the same place. And yet they understood each other better than anyone ever could. And than... Anime, just, ends. They just do what they must, and move on, never to see each other again.
