Eh, most series try to escalate the threat with the next being larger and more dangerous than the previous one. That Giants and Gaea were toted as being a bigger threat than the Titans. Yet, the Giants failed to accomplish anything on their own, were less powerful than the Titans, lost to demigods in single combat which the Titans didn't, and never came close to being the threat they were supposed to be. That is one of my biggest disappointments with the series.

Gaea supposedly was the main threat, but she too went down easily.
