I watched it until they finally finished saving the bridge builder after the 'fight' had been dragged on for several episodes (DBZ-style). Decided to stop watching after that. I later discovered that the "filler" which most people complain about had not yet even started at that point.
That's just my experience though, you might like it better. The general idea sounds great (Sasuke is pretty hot too), but it seems as though the writers had frequent vacations, resulting in a lot of episodes that could have just been left out entirely.
