A better value than the first DLC, but I still can't help feel this should have been included with the original game.
Luckily, the cost of the DLC is small, so the indignity of paying for something you should have gotten for free is lessened. Unfortunately, the DLC adds no new achievements, so there is nothing really to be gained by completing it beyond being able to say you've experienced all of Ezio's story. If you buy the "deluxe" version of this DLC, you'll also get the bonus locations from the special edition that are similar to Prince of Persia dungeons.
I can only recommend Bonfire to AC diehards who enjoy playing the game regardless of the cost. There's really nothing wrong with these missions beyond having to pay for them.
