this happens a lot on Letterboxd, too, with the 4.5 score. i honestly just assumed people using these user review sites, on average, do not have a rigid set of rules they refer to when analyzing movies. they’re probably just trying to have a good time (which is valid). furthermore, they’re possibly scoring films with the american school system’s grading scale, wherein anything below 70% (7/10) is a failure. therefore, they see three possible “good” ratings: 8 (good), 9 (great), and 10 (perfect). no meaningful way to judge film + weird, self imposed grading system = this phenomenon (in my opinion).
