Wow. Wow wow wow wow wow. This show has got to be one of the coolest animes I have ever seen.
Story: This story was so compelling. I was interested the entire way through. Seeing as there are only 26 episodes, there was obviously going to be some places that could have been developed further - sure. But the plot they present and care out is so well done and interesting that it just makes me wish for more seasons.
Art: Alright, some people say 90's anime art is not that awesome but I totally disagree. I like the thin, 'scratchier' lines and gruffer design. The style of the art really suits the whole feel of the show. I think they did a great job with keeping it consistent with the manga artwork.
Sound: HOLY MUFFINS! The music in the show was perfect. PERFECT. It suited the style and feel of the show in its entirety. Actually, the music is part of the reason I actually decided to watch this. I was on the fence when I started the first episode. But as soon as I heard that opening guitar riff, I was all " HELLLLLZZZ YEAH"
Characters: Vash has to be the coolest character to ever be created in the history of ever. Seriously, he is such a dynamic, complex character that he basically makes the show. This show should be "VASH and co" because, let's be real, you watch for Vash. He is the most endearing badass I have ever seen.
Ok ok, the other characters were great too. I loved Wolfwood. I liked him almost as much as I liked Vash. And Millie and Meryle surprised me. They could be a little annoying but I liked that they actually had distinctive and unique personalities.
Enjoyment: I gave this an 8 because, while I love the show, I definitely had to watch it in small intervals. I'm not sure why. But I think that after watching a bunch of episodes in a row, the uniqueness wears off.
Overall:
Definitely watch it. Its a classic for a reason, you know! Everything was top-notch - even the dubbing ( I rarely watch anime in English dub because...well, it's normally just so bad that its kinda painful)! But there are a few dubbed gems out there and Trigun is one of them!
