I liked the armor portions from the time, and some of the other accessories, but like others, didn't care for the He-Man sword. I also disliked the huge reliance on BURP-style parts and the overuse of Black, which has limited usefulness in most castle themes. Between it and Batman, I have more black bricks than I know what to do with.
Since then, Castle has gone back to its roots, and has gone through a much needed transformation, still having some of those story elements but capturing what made it such a good line in the first place.
You know, if I see links to Brickshelf, more often than not, the first thing I click is the "Back" button.
