Pros:

The following DO change:
~Dead Center
~Dark Carnival
~Swamp Fever
~Hard Rain
~The Parish

*Anime images are a plus in my opinion (I know it's biased, but just saying)

Cons:

The following DON'T change:
~The Passing
~The Sacrifice
~No Mercy
~Crash Course
~Death Toll
~Dead Air
~Blood Harvest
~Cold Stream

*Also, because of the dimensions of the images in relation to the game's resolution; the images look distorted.

Conclusion:

It's a good idea, even though some of the loading screen don't change and the fact the images look "stretched" to fit the game's window.
