I loved the original so heavily biased; yeah, I think the new content is overall worthwhile.
The 3rd storyline is definitely a missing piece, after the original ended without an actual resolution to the crux of the game's conflict other than "yeah we're trying to figure it out and solve it, maybe someday".
And yeah, the (((DLC))) is something of a downer, but it's more cosmetic than anything. There isn't a whole lot of additional story content there, and even then it's only $13.95.
