THe Hobbit ones I find generally rather boring despite a few good tracks.
I find the first Hobbit score is really a nice listen. Best in that trilogy. Probably also due to the extensive usage of the indeed best theme not by Shore.
In both trilogies I mostly struggle with the second score, same for Two Towers and Desolation Of Smaug.
The first and the third I enjoy quite a lot in both cases.
