I really like CLAMP, they make some cracking anime (and manga I'm sure) but what the heck were they on when they wrote the story arcs for Tsubasa?
First series, pretty good, kept me interested.
Second series, WTF? Almost an entire series of filler! Seriously? what were they thinking? 52 eps in and they've not got to the reasons why the characters are where they are.
So in a last gasp I pick up the OVAs. 5 extra eps. Oh look, they've finally bothered to get back to the story arc that started in ep 2.
One of the cool aspects of Tsubasa is they've had an excuse to include a lot of other CLAMP worlds. Bits from Angelic Layer, xxxHolic, X etc.. Don't think there was any Chobits.
Now... do I import xxxHolic series 2 and the OVAs?

Poor Watanuki.
