On the other hand, they're the new oblivion gates. There's far too many, far too often, and you often times can't avoid them. Also, I have several times had the wrong level of dragon spawn. Like getting a random elder dragon on a lvl 9 character. Almost couldn't even run away from him. Plus, I got the most frequent dragon attacks AFTER the main quest. Something like 12 in the first 30 minutes after beating it. They should become LESS frequent!
Overall though, I'm glad they're in. If you don't like it, push through the mq, start a new character, and don't touch the mq anymore. Poof! No dragons.
Oh and another problem with dragons,
Spoiler
Alduin is the easiest dragon in the game
