Gungrave: A Thrilling Action Anime That Needs More Love
Gungrave's story is by the manga artist Yasuhiro Nightow, who also did Trigun.The manga was first adapted into a video game for the PS2, and the anime borrows from the game. Viewers familiar with Trigun will notice similarities. For example, both have a nearly invincible protagonist caught up in violent conflict he doesn't want to be involved with. But unlike Trigun, with its hippie-ish optimism and goofy comedy, Gungrave has an overall tone that is more brutal and serious.

I would recommend it for fans of more serious, violent anime, similar to Hellsing, Trigun, or Berserk. Each episode was interesting, making you emotionally invested enough to want to watch more. The story starts in a present moment, but then everything that follows is one long flashback. This shows how things got to the state they are in in the present. It's an innovative storytelling technique that got me interested in the characters' lives. It kept my attention. I'm not sure I would call it truly great, but it was worthy entertainment.
