HDMI / Blue rays is "good enough" for just about any movie ever filmed.
For new films, while the 4K spec is interesting and may be useful for theaters and large home screens, a more useful and visible improvement would be to shoot at 60 FPS instead of 24 or 30. The smoothness is readily apparent, and is visible at any resolution. IMAx makes good use of this frame rate and some of the images, along with a large hi-res screen, are stunning.
BTW, it took a dozen tries to figure out the Captcha code.
It doesn't have to be this difficult.58Hcmw7
