well, what i can say now is that the cliffhanger at the end is not as bad as i imagined.
just finished last episode. it pretty much concludes the visions guts had in the first episode and the mark he has, and what happened to his eye.
ofc much is unanswered and its open ended, but for me its okay, happy ends are overrated and i was able to enjoy every episode for what it was
eng dub was done rather well too.
after finishing it in 2-3 sittings, i will wait with checking out the manga however. from what you are saying it sounds like its something to look forward to
