I found the Positive Film effect, with a bit of fiddling with contrast/vividness and white balance settings (moving it slightly to the warmer side), delivers thoroughly enjoyable results, to the point that I don't miss shooting real film anymore.
Up to now, I was not able to recreate the Positive Film effect in Lightroom, even using the famous film-emulation presets out there as a starting point. There is a sort of smoothness that the Positive Film effect applies to the skin, lightening the shadows ever so slightly, bringing the colours on the pinkish tone rather than harsh digital like green tones, that I've been unable to emulate in LR.
Incidentally, this is causing me disk space problems, as I don't want to delete the jpeg files and at the same time I want to keep the raw files too.
I might have to buy a bigger hard disk because of the Positive Film effect
