I finished it yesterday and to be honest I must say that I'm actually a bit dissapointed. The MQ isn't very long and you didn't even get to fight the bad guy.
The only villain you get the pleasure of killing is the fanatic in the paradise, and he was way too weak anyway.

And I was only level 13.
But atleast I don't have to worry about those Oblivion Gates anymore.

Kinda like Morrowind then, you can finish that at a very low level too. I just fail to see the fun in that.

I agree.
I think that Dagoth Ur was a much better bad guy. Manker Camoran didn't seem to be very well developed as an end boss, imho.
