I enjoyed this manga quite a bit. Its essentially the typical shonen manga, with little to differentiate it. What i enjoyed was the bizarre undercurrent of evil it seemed to have at times. From an almost necrophillic doctor whos implied to be addicted to Morphine to a boy quite obviously named for a drug ( Lyseig Diethel named for Lysergic Acid Diethylamide respectively)

I also found many moments to be extremely emotional and touching, wihlst the characters were well characterised and varied, each with their own personalities aims and backstories, some of them just tragic (especially that Doctor). The characters come from various countries and ethinicities, which makes a good change from casts inexplicably scattered across the world yet all japanese. Theres English, Chinese, African-American etc. its nice. Best of all, the villain to this piece is a marked change from most villains and a breath of fresh air against the common evil to everything type you get in some manga.

So if your bored and want to read another shonen manga, i would suggest this over most others.
