I know most of the Kanzenshuu users feel like these Season sets are too "clean," as there's literally no grain remaining in the picture due to FUNimation's remastering. But if done right, no grain doesn't inherently mean no detail. Look at animation cels. They are basically the original source, before anything is even put onto film.
The Orange Bricks were a failed attempt at cleaning the footage to look like cel-quality, modern footage. It was awful and we all know it. This Blu-ray "Season" release, on the other hand, is, for the most part, gorgeous, if you can get past the widescreen aspect ratio and lack of grain. This type of remastering is probably the closest we'll ever get to a cel re-scan of the show.
I can say this (as my opinion, obviously) as I own the set and have watched the first 15 episodes. Shots that have diverse color palettes look fantastic and characters and important objects are usually well defined and sharp; definitely worthy of high definition Blu-ray.
My biggest beef(s) with the remastering happens when colors of certain brightness' are too close to each other. For example, when black is next to dark blue or dark green. Occurring particularly during nighttime scenes, the darker of the dark colors sometimes results in details not being visible. This was worst during some of Gohan's wilderness survival episodes. Similarly (though far less often) some of the brightest colors, if set next to white, looks far too white. Fortunately, this seemed most apparent during Kame House scenes of the first few episodes and hasn't been noticeable since.
To be honest, I'm okay with the set's only negatives. They are issues, but they're ones that could easily be fixed in future sets, since it'd only require a simple adjusting of the contrast setting (or saturation? I don't know.)
Anyway, I just think people are complaining a whole lot when they haven't seen the footage in motion (outside of YouTube videos, which truly does not do the footage justice) which I understand is their opinion, but it's just difficult to see their perspective when most haven't given it any sort of a chance. In truth, I was like them before seeing the first screenshots. I was 100% prepared to hate this release, but upon seeing the vast improvement over the Orange Bricks, I've completely changed sides. I still see the negatives that exist (yes, I acknowledge that it's not a perfect release ((there's no such thing))), but the positives FAR outweight them in my opinion.
