Sunabouzu is, imo, one of the best animes out there. It's got action, adventure, comedy, perverted comedy, and a good plot. Before I started watching it, I thought it would be a decently good show that didnt get a lot of traction. However, upon finishing it, I am really surprised how such a great show has a rating lower than it deserves, and isnt popular at all, even for a 00s anime.
Story - 9/10
It's got a great stor in a desert dystopian setting, although the story takes half the show to develop (which I think is a common trait for most shows during this time period; first half is episodic and filled with humour, while the second half gets to the solid plot, and probably has a sad/bittersweet ending). If you like dystopian stories, or plots about humanity regressing back in time, then this is perfect for you.
Art - 10/10
The thing that attracted me to the show initially was not just that it was similar to Trigun, but the artwork. The animation isnt the best, but the art and colour palette was satisfying for sure! Just showing the desert during the day, a bright yellow to represend sand, and a bright blue to represent the sky, was aesthetically pleasing. The art feels smooth, and not forced. The animation was also pretty decent, and as someone who loves 90s and 00s shows, this was all I asked for.
Sound - 8/10
The first half had one of the best OP and ED easily, while the second half wasn't good imo. The background music during the show was decent, not great, but it still added to the mood of the show.
Characters - 10/10
The characters made this show very enjoyable. You have Sunabouzu, the protagonist, who's extremely skilled, but equally perverted and moronic. His student, Taiko, shows a transition in character from a helpless child to a shrewd and cunning girl. Asagiri Junko is another cunning woman who uses people to make her ends meet. Amaguro is another legendary character who packs good action and humour. Overall, it's the characters that dominated the show.
Enjoyment - 11/10
Overall it was very enjoyable and always kept me wanting more, which is the best thing an anime can do. It's got the setting of Trigun and the humour and characterrs of Golden Boy. Definitely a 10/10 for me overall.
