Darker Than BLACK

Seriously impressed with this one, its so rare you come across a really good Anime like this nowadays. The first season is really, really, really good.
The second Season was dreadful, so dont watch it if you can help it. The OVA's were OK but not anything satisfying as they didnt really tie up any loose ends.
Many of the fans are still hoping for a third season, although its not likely.

I thought it started off cool, then sucked on an epic scale as it progressed. I mean, it looked pretty unqiue to begin with, but then bogged itself down with so many anime sterotypes I wanted to cave my own skull in.
