I have to say I disagree with some of the extreme negativity about the scenes remade, some went on to say game is sure to die soon because of it, and that is complete nonsense to me.
I will agree that some of the recent animations have lacked "range" in the movement, but that could be accounted for the specific view the artist had of the scene, now, however, comparing the original doggystyle scene, the facefuck scene and the cowgirl scene to the new versions, it's clear it's on purpose. I couldn't tell you why that is, but it seems to me the problem of lack of "range" as well as bounce or jiggle to the new versions, could be corrected with one additional "speed increment" on each scene, which would feature the full range of motion (as seen in the fastest version of each of those scenes), and therefore the collision and bounce that seems to have been avoided in the newer version.
That being said, even with this big room for improvement, I'd say the newer versions were all big upgrades from their original counterparts, especially the first handjob scene with the sister. Not to mention the inclusion of the new (also remade maybe? Don't remember it being a thing before tho) dream scene, which could also benefit from the improvement mentioned earlier, but was still very enjoyable.
Also saw someone against the visual update and the scene remake to Ms White design, that I suppose is much more based on personal taste. Personally, I did like her new design, as well as the new BJ scene.
EDIT: I do however agree with the sentiment of prioritizing NEW content as opposed to revamping existing scenes.
