This DLC was a bit of a letdown, not bad but very thin. The Pale Reach was just lacking in personality compared to the other areas- only a handful of new fish are introduced, a single new enemy (who's kinda lame, I basically ignored it), and the mission in the area is extremely straightforward with no twists. The base game has such a tight narrative so I understand why they didn't try to tie this in but it is noticeable how disconnected the whole thing is from the rest of the story.

The refrigeration mechanic and the reward for finishing the area are great and would have made the game a lot easier- I was playing on a completed save so they weren't much use for me but it'll be an asset for new players.
