xxxHolic, in my opinion, serves as a continuation of the main series, but exactly how well does it do in that regard? For starters, everything about the series is relatively consistent, and it appears that the status quo has been restored since the ending. Allegedly so, anyway. With this brings back a fair amount of the original manga's pluses and negatives: pacing, writing, how much you like the characters, are all hit-or-miss for the most part, and this is large dependent on how you felt towards the main manga as a whole. If you enjoyed the main series, you will likely enjoy Rei. Unfortunately, somemain series characters don't return (at least as impactfully) and the series is unfinished, like Cardcaptor Sakura's Clear Card anime. If you enjoyed the original xxxHolic, you'll likely enjoy this, but otherwise, it doesn't necessarily add anything that hasn't been seen before. 6/10.
