This is the season BSD takes a big leap forward and starts getting juicy. Things start getting more serious and there is more of a central plot than the previous seasons. U also get some good backstory on some characters and the Armed Detective Agency as a whole. Anyone who says it follows the same formula as the other seasons, i'd have to question whether they actually watched the entire series to this point... this season has a different feel than b4 and is simply better than previous seasons, as is evident by the 8.45 score. That's one hell of ascore, and it deserves it.
