I was unaware of the discord over those movies in 4K, to be honest. I wonder though if those same critics were watching said movies on a properly calibrated UHD display, with all picture setting modes (HDR, DV...Filmmaker Mode) properly calibrated for all inputs...and or if they weren't "coloring" the pictures themselves using a 'vivid' mode or using such "features" as Dynamic Contrast, Dynamic Color, and or Dynamic Tone Mapping (DV being the exception).
On a side note, I've seen the Aliens 4K movie (bought a physical copy) and I didn't notice any issues or problems - the film looked great to me. I also loved the Blu-rays of SDFM and DYRL?. While the animation of SDFM hasn't aged well...the show looks absolutely gorgeous in my eyes - they did a phenomenal job with it, in my opinion. The only disappointments I have ever had with any Macross Blu-ray I've bought is the censoring in DYRL? and the English subtitles in Macross Plus; I'm glad they re-released DYRL? uncensored.
I'm still hopeful and confident they'll get it right with this 4K release.
