Back In The Day, I used to listen to a lot of CCM. Not all of it was dreck, though there was quite a bit that was really terrible.
Some of the earlier Michael W. Smith and Amy Grant weren't bad. The more "pop"-y they tried to get, though, the worse they became, and Grant's "Heart in Motion" album was a travesty from any direction you looked at it.
Petra and Sacred Warrior were (looking back) not particularly good, and Seventh Angel was downright bad, but their rock sound helped me (an angry teen who was searching) transition in from more mainstream rock. So there's a place for all of that stuff. Ultimately, if the music reaches someone, and helps them, then it's doing its job, even if it's not music that you like.
