Lurid, brutal? IMO, no. I honestly think the train picture is too saturated but the high saturation really suits the winter landscape (though a monochrome conversion might be worth trying?) And, given that light, the seascape would have been hopelessly "flat" on Astia, even if the representation it gives would be more accurate.

I guess what it boils down to is that when film is loaded, especially colour transparency film, it needs to be matched to the subject and the light. Digital image capture frees the photographer from that restriction. Printing processes, wet, digital or hybrid, can of course foul up the photographer's intention ... if you want control then you have to wrest it from commercial processors.
