Not all circumstances are worthy of a high quality picture... Even with all the dynamic range in the world, your prints will be limited to about five stops of contrast at best. Subject matter that isn't too high contrast and is dynamically lit and shaped produces a better print... Compare a landscape shot at a nice hour or a portrait shot with nice light with a tonemapped HDR photo of the same. The HDR looks terrible because even if you have it all in the "negative" you don't have it all in the print. Something will get sacrificed: tonality, contrast, or shade-based depth cues. You can't have it all.

Even pretending to have it all is its own art, and arguable one of the finer ones. Generally in extreme circumstances in which additional dynamic range can be captured and printed effectively it's done with extreme painstaking planning in both post and when taking the shot. Zone system for landscapes, "painterly" work like Crewdson's (which is a bit overrated, imo!) for more modern, "cinematic" photograph, etc. This involves a lot of reliance on the light and then using HDR techniques (dodging in burning on the print or digitally) to complement the light, not make up for its deficiencies.

The current generation of Red is not so great, either. Bad memory colors (plastic skin tones and issues rendering foliage) and some issues with the compression codec blurring high frequency detail. The low light performance is also dramatically inferior to what Canon gives you. If the current generation sensor were so great it would be used for more still photography, but still sensors are just as good when given the right subject matter, and the fast AF and flash sync are worth more than a little more latitude in poorly exposed shots. This next generation will surely be better... but likely not materially so for low light. This may just be personal bias, but I find photos from my Mark III to be vastly prettier to stills from Red footage.

The Red, properly graded, can produce breathtaking video, however. I am very fond of the photography, for instance, in Prometheus, and the film is a technical marvel.
