Sadly things are going downhill. After seven books with no new ideas things have become stale. Not even the reappearance of Harry at the end of the last episode can redeem things.
The art style appears to have changed too, becoming less detailed.
There are some nice touches here and there but not the great mystery that still appears in the series title.
There is also another Halloween special but cameos like Constantine just seem like elongated adverts for other books.
No Thumbs.
