The DLC is hopefully half-way decent after the first two misses...
I don't know how you can call Dead Money, and Honest Hearts misses.
I hated Dead Money on my first play through, but playing through again I absolutely loved it, and it really was a fun Fallout experience. My bad experience with my first play through on DM was based solely on the fact that I was severely unprepared for what that game threw at you. It really made me appreciate the Survival skill, which up until that DLC I didn't give a crap about.
Honest Hearts, sure it was a little light on story, but Zion was beautiful, and the game play and exploring was pure fun. Not to mention getting to meet one of the most awesome Fallout characters Joshua Graham, and the story of the Survivalist which was intriguing itself.
