"Monster" is for those who love the "cat and mouse" concept, and for those who get a kick out of the mystery, psychological, and intellectual-type anime. It's also quite easy to follow and you will definitely sympathize with the characters - except maybe Lunge. But if you find him annoying, don't worry - he gets better much later!
Ever wanted to watch an anime from the perspective of the chased? Here it is. There's an American film that has a similar plot - I forget the name but if you watch it, you'll instantly identify traces of "Monster" in it.
So anyways, this is a MUST WATCH anime. Especially if you enjoyed anime like Death Note. I would rate this higher than Code Geass, which was good but probably not as enjoyable as Monster. All in all, Monster deserves a 10/10 as a nice, sufficiently long and developed anime - it certainly makes my list of top 5 anime of all time.
