Morrigan is so hard. It's like 

'I like your hair, it is pretty' -10 points.
'You are an evil whore witch!' +30 points.

I tried romancing Morrigan on my first playthrough of the the game, and on that first playthrough I was also going as the 100% good character, so you can imagine how difficult that was. The answer: gifts. Lots and lots of gifts.
