The reason the Deus Ex Human Revolution bosses were unfaithful to the original source was that the game itself was outsourced to another company to create the boss battles so it didn't really follow as close to the other work done on the game as it should have. Now remember that the reworked bosses is incredibly important for this DLC and the main selling point for many fans.

If you own DLC on top of that it goes from 10 to 5 dollars. They will also slash the price of it from 20 to 10 if you own original game. You will end up having 3 games in total because of this (assuming you have Deus Ex Human Revolution and the DLC before buying director cut.) It will display in your library with (Deus Ex Human Revolution, Deus Ex Human Revolution Director Cut, Deus Ex Human Revolution: Missing Link)

Multiple Games Displaying Instead of Merge in Steam Library Generally, you could have missed the point where it was "logical" to play the DLC since its at a specific point in the story. However director cut combines them both into a single game so that it has better flow and feels more natural with the story. First you must understand that the Missing Link DLC and original game were treated as separate games in your steam library.
