This is not a bug; it’s a feature. Compare a "Smurfs 720p" rip to the official modern CGI movies. The former feels hand-made . The latter feels sterile. The search term is a rejection of the sterile.

The popularity of this search term correlates directly with a distribution failure. For nearly a decade, official Smurfs DVD releases were either incomplete (best-of compilations skipping "problematic" episodes) or poorly transferred from battered PAL masters.
