Is dot Hack actually good?

I've been avoiuding Dot Hack in all it's forms.  Is it worth it to play through all four games, or just avoid it?

Terrible, and a total lack of caring on Bandai's part didn't help. Thought it would be like a Bethesda game. Nope. MMO clone with more retarded 'players' and without the ability to slay them in an instant. Also for something that's supposed to 'emulate' an MMO, people sure do repeat themselves a helluva lot.
