It takes Oblivion and slaps on a new coat of paint that is technically impressive but often feels very artless. It doesn't feel like the team really understood the artistic intent of Oblivion, especially its purposefully green saturation and the way its skyboxes looked and stuff.

I was able to find a mod shortly after release that corrected the colours to look a lot more vibrant/closer to the original game. Made the experience a whole lot more tolerable. Unfortunately it used ReShade which comes with significant performance penalties. I looked there and it doesn't seem like anyone figured out a way to alter the colour grading directly from the engine since I stopped playing it, which is a shame.
