Thanks for the replies guys.
Since the majority who posted here gave RtO a pretty positive nod, I decided to grab it.. and I have to say I'm extremely pleased I created this thread, because otherwise I might have skipped out on what was a very enjoyable couple of hours.
I honestly don't quite understand why this DLC has been so badly panned. Like Galraen, I think it's the best of I've tried.
It's very good value for the money, and I like the way it ties into the main game. When you left Ostagar the first time, there was something raw and unfinished .. at least if you roleplay and enjoy the storytelling aspect of RPGs. RtO provides closure, especially when you have Wynne and Alistair with you.
There was also a certain cut scene where I actually felt moved... OK, maybe I'm just a cheap date when it comes to emotional manipulation.. but I felt that scene (and I'm sure everyone knows the one I'm referring to) was very well done.
And yes, the dialogue between Alistair and Wynne was great!

(if not a tad disturbing at the end

).
I don't know, maybe it's because in RL I prefer to resolve loose ends when I can, or maybe I'm overly enamoured by Dragon Age

o), but I definitely thought RoT was worthwhile. So.. many thanks for the recommendations!
