The show is just not very good, as it uses typical shounen clichès, such as overblown reaction, stereotypical characters and very obvious storytelling techniques that can only impress people who enjoy mindless Hollywood movies. The bad guy laughs manically, think he has the upper hand, then Akagi smirks, explains how he's played his game and shows a winning hand. Rinse and repeat.
Basically, if you enjoy good movies and can see through some very old and tired film making techniques, I suggest you stay away from this one.
If you're easily impressed, then by all means, enjoy Akagi for what it's worth.
