While I don't think Trigun is bad by any means, I do wonder how I feel about it these days, since I last watched it around 7 years ago and this was when I was just really getting into anime (had only seen around 50 shows prior) and thought it was really fucking cool and had some really interesting episodes and fun action. These days, I wonder if I'd find it somewhat bland and not as fun?
Great opening though, entire reason I watched it back in the day. Some anon on /v/ said it was his ringtone and it interested me so much I had to give it a watch.
