I will tell you why you got dislikes. Honto Yajuu came out in 2008. Brothers came out in 2001. And it's pretty easy to see that the author of Honto Yajuu is the same author of Brothers. The art looks way too similar for it not to be. For example, with Harada sensei. You can always tell when Harada is involved/creator of the work because of their certain kind of style in their art.
Okay, I am done rambling. (づ ̄ ³ ̄)づ
Don't sweat the hostility. Most asshole commentators either can't understand complex English or are lonely and need attention. The rest of us understood that you were complimenting the mangaka on their improvement over the course of time when some mangaka's works have devolved. An artist who truly enjoys the work will continue to improve right up to the end, unless something like illness bars them from doing so. Others, who do it because they must eat, will slowly begin to become sloppy and careless. Obviously, sensei truly enjoys the work.

I never realized that the prequel of this was written by the same person who writes Honto Yajuu. Man, has their art improved!
