I reckon castle is the best of the modern lego lines. But thats just my opinion.

It's true that, for their price and box size, many lego kits these days are very underwhelming. The size of the boxes being the most misleading attribute. The Skull tower isn't really a 'castle' sized kit, more of a 'tower' kit. The actual kings castle set is the largest castle set in the current line but I don't expect it to be any less underwhelming.
