It is, actually, and amusingly enough, the first time it comes up, Shirou's reaction to the idea is a rather obscure reference, something to the effect of "Crowley and that tantric magic stuff was a load of crap!" But, while I put it somewhat ambiguously, I suppose I should clarify that Nasu's general treatment of the concept tends to run the gamut from the normal if a bit strange (Rin and Shirou forming a link so he can use her magical power in the final battle of UBW) to the "wait, what's going on here?" (Rin needing to join in on the threesome in the church in Fate because otherwise Shirou and Saber won't be properly 'synchronized' by having orgasms at the wrong time)to the completely off the wall (the aforementioned backstory of Heaven's Feel, wherein apparently "evil magic-draining parasites" = "me so horny!") It's ironic that the last, which is the most bizarre of all of them, is the one that seems the least out of place, given its overall role in the plot.
But nonetheless, Heaven's Feel is a storyline I imagine would be somewhat difficult to translate to the screen without losing either a chunk of the plot or making it whatever the Japanese equivalent of "no one under 18" is. Which, admittedly, they could do, given what we've seen of movie adaptations of Kara No Kyoukai (Lingering Sense of Pain has scenes that are actively discomfiting without showing all that much), but Fate's been marketed *away* from the more sex and violence drenched areas of the fandom, oddly enough. It'd be interesting if they ended up adapting HF accurately despite that.
