Firstly, this anime is not for everybody, this is a Seinen,and a real one, this is not only about Blood and more blood, like everybody thinks a Seinen must have. This is the story of a simple man, an amazing man fighting for survive and for a better life to his family. It sounds kind of heroic, but it's exactly like that. If you have watched GTO, and you've liked it, you'll love this one. I'll analyze some parts: __________Story__________ The story is amazing, you'll like every single part of it, because you have a lot of stories in it. You only can watch the businessman story, theflashbacks, the romance story, the conspiracy...seriously, amazing. It's one of the best plot I've ever seen in an anime, why? Because it's realistic, there are no angels, demons, mages or wizards, there is just one thing which keeps the world moving: Money. And this single man, will fight with only his reputation and his hardworking.

___________Art_____________

This is not a new series, It has some bad feeling on the art. Furthermore, the way the characters are designed, is very interesting, they look like real japanese, I dont usually like the anime where there at least five blond guys who are "japanese"...

__________Sound_____________

Anything remarkable at it, not bad, not excellent. It wont disturb you.

___________Characters_____________

Here is the story relies it power. Like I said, THIS IS A SEINEN, we dont have a laim protagonist and pathetic who is a wimp, but we dont have either the perfect guy... We have one of the best main characters I've ever seen, it's almost at the level of Onizuka. Why? He keeps changing, improving or getting worse, he is wrong or right, he has his own moral but he also knows when to be quiet...He is a guy who despite losing his lover, follows liking women, and he treats them as a real man should not as a wimp. (In this, he wins over Onizuka). He has a patternal side also...Seriously, amazing.
On the other side, we have several badass, a manipulating "Oba sama", an amazing female lover (OH MY GOD, I felt in love with her when I see her), a boy who acts as a boy, a funny workmate, a lot of funny ex-riders...
For me the story is a 10 only because of its complex net of characters.

The enjoyment is something subjective as everything else, but what I can assure you is : This is not a waste of time, this is worthy.
And for me is:

An amazing Anime.
