This update is the definition of a mixed bag.

On one side, we have some terrible dialogue, annoying chalenges, an even bigger lack of polish than the one present in the base game and many additions were redundant.
On the other, we have probably the best final boss theme in the entire franchise, and believe me, it made it all worth it.

Edit: actually thinking about this dlc again just made me remember how bad it is, final boss theme is great but the boss itself sucks and the ending is overall worse than the original.
