Depends on the movie. Pretty sure pores weren't problematic for Avatar, or March of the Penguins, or many other movies. For the majority of movies that do focus primarily on humans, there are typically still scenes (e.g. outdoor panoramas) that clearly benefit from high resolution. And a competent film crew should be able to soften the look if it is appropriate. It's slightly absurd to suggest that 4K is the max resolution we should allow because some films might be diminished by the use of 8k.
