The storyline is so weak, the viewer often feels as if he's watching a documentary of something. There's no connectivity in the episodes, and the fractal appearance of the whole series will put everyone (except the most devoted .hack otaku) off. The story doesn't have heads or tails; it just plods on, like an excrutiating torture session.
The character design's very weak as well. Though the lead character, Haseo, is created well, flaws in his conceptualization leave him with a schizophrenic character set. Shino and O-van, the other two lead characters, are far better in their conception. O-van, particularly, is a great character, sort of like Hatake Kakashi in Naruto or like Urahara Kisuke in Bleach. Besides these two exceptions, everyone else is useless as characters. Tabby is too smarmy, Sakisaka too vacillatory, Ender too non-violent, and Filo too plodding.
The one high point of the show is the music, produced by Ali Project. The OP (Silly-go-Round by FictionJunction YUUKA) and ED (Boukoku Kakusei Catharsis by Ali Project) are awesome, to say the least, and the INs never fail to enthrall either. IMO, do look out for God Diva; it's a superlative track. Silly-Go-Round, thanks to its catchy tune structure and fine alterations between the violin and modern instruments such as the guitar or drums, makes for a great listen.
Sadly, the music is the only thing we reviewer otaku can rave about. The idea behind the characters is good, and as in the case of Tryedge, almost exquisite. But there is no clarity, no Ichigo-esque madness, no Naruto-style idealism in this story. One misses the clear objective reality of Bleach or Ghost in the Shell (or maybe even the earlier .hack iterations?). There is virtually no action, no drama, no flesh and blood; in short, there's no juice to this baby.
Who do I recommend it to? No one. This anime (as much as it pains me to say it) is simply unwatchable. Don't watch it at all, except maybe the first episode and towards the end. The rest will simply bore you, and make you regret the time you spent downloading the episode. .hack//Roots is a total failure for me.
