I suppose we essentially agree. 😃
Of course, it’s a matter of taste. I’d welcome a bit more detail in darker areas but the gritty look is really neat and literally a nice contrast to the more video-like experience with the HD versions. Unfortunately (or luckily maybe as otherwise I’d be even older than I already am) I was too young to watch True Lies in the cinema, but I guess this was just the way it looked.
Will be interesting to see what they do with any official Blu-ray* release if Cameron ever cares to get it done instead of planning half a dozen Avatar sequels.
(*) considering how late they are, they could skip it right away and rather dump a 4K scan from the negative onto UHD. 😉
