I stumbled across this gem while late night channel surfing, entering at the scene where Amanda and Nathan take the "detour" which lands them behind a pigeon truck. I'll admit what caught my eye was Julie Condra's beauty, but the story was intriguing because I knew neither how it started nor that it was a Christian film. The bad guys were caricatures, her boyfriend was pathetic, and the medical details poorly researched (hey, I'm a doc - I notice these things!), but it was fun, engaging, and mostly well acted and well written, with a message that did not feel forced or contrived, and with what felt like a natural relationship evolution between Nathan and Amanda through the film.
Perhaps the best evidence that this is a film worth watching: after it ended, I channel surfed a bit more, and came across a Girls Gone Wild adfomercial and VH1 music video. The contrast between the peaceful spirituality of the final scene in R to R and the raucous tawdriness of GGW and VH1 was stunning. I prefer the former. Much more.
