Not your average DLC. This one's for the fanboys and the people who wanted a 'happily ever after' with Morrigan.
Ofcourse many people had characters who didn't romance Morrigan at all, or even hated her, so it doesn't really make sense to devote another game to that. Still I was disappointed and lent my voice to all the hue and cry the other fanboys made about the change.
So now this DLC. If you didn't romance Morrigan, don't get it. It's without that plot, it's useless. It is short, it is shallow, and I wouldn't have given it a 5 even. Get Leliana's Song. That's way better.
On the other hand if you did romance Morrigan and kept her ring, and if you want a chance to say one final goodbye to her and your Warden....or even get some sort of happily ever after for both of them (trust me, you can get a happily ever after...relatively speaking), then get this DLC. It isn't the grand send off one might want, and it does pose more questions than answers, but still, it's worth it.
There are a few 'enchanting' cameos. And I'm also sure if one plays as a mage or a Dalish elf, there's some extra dialogue.
Bottom line is that this DLC isn't for everyone. It's Bioware's answer to the outcry of Morrigan-Warden fans who just weren't ready to let go. And for that I am grateful. If you belong to the mentioned category, get the DLC. You won't be disappointed. If you don't belong, don't get it, for then you most certainly will be disappointed.
