Well...
I give you DTB2 plot wasn't that good; the whole pseudo-apocalyptic setup felt kinda forced... even a little bit phony... but...
I loved the characters (both the char-design and development), especially how "old" characters evolved... and Suou of course <3
And I also loved the narrative... but I guess this applies for dtb1 as well
overall, the whole series (dtb1, gaiden, dtb2) were absolutely amazing, I liked them a lot
thanks again =)
