Empty. It was too sudden, I didn't get the feeling of closure tbh.
I'm not a big fan of Bleach. Actually it's the one I like the least from the HST+FT, as in, I love Naruto, One Piece, Fairy Tail equally (sometimes I love one more than the other, I like FT over the others at this very moment), and then >> HXH >>>> Bleach.
I watched the Bleach anime. It was "difficult" for me because I didn't enjoy the series. There were parts that I liked but overall, I just watched it because I wanted to watch the HST, not because I enjoyed it. Then when the anime finished I took up the manga by the equivalent chapter after the anime ended. I began to just look at the pictures and stop reading the text many times. I didn't care about most explanations tbh, nor powerscales.
However, I expected a much more fulfilling ending.
