OK..I don't know what's happening, but here's what i see in this thread:
The original shots are a bit too dark and too saturated, and there is a magenta-purple cast to all of them.
The version of charjohncarter is a bit brighter but with a strong blue-cyan cast.
The versions of myoptic has a gamma too high making the images look very flat, contrast-wise, and there still is a cyan-blueish cast on them.
(My monitor is a lower budget one, but calibrated.)
I've only shot a few roll sof velvia in my life, but the image of endustry is the only one which resembles the colours I got on velvia.
In conclusion, i think it's not only the film. A lot depends on the exposure, the development and especially the scan/postprocessing since we see these on a monitor. E.g. minoltist and wjlapier show some frames with absolutely normal and nice colours without oversaturation or any colour cast.
Here are two of mine to support my blah blah with some coloured bytes.
