I agree 100%.
Elvis movies are most times basically Elvis performing several songs with a skeletal storyline cobbled together to link the performances together: NLT games boil down to a male individual (MC) performing heterosexual sexual acts, often with multiple partners, in risible and often ridiculous ways, with a weak storyline cobbled together to link the scenes together. Naomi is basically a one-dimensional stock character, i.e, nymphomaniacal, self-centred, catastrophic and manipulative older woman, used as a shortcut in the plot to trigger a sexual scene, between the MC and one or more female characters, acausally, which the storyline hasn't got the time or can't be bothered to justify.
Naomi IS boring because her hypersexual monomania means that she only really cares about indulging in sex, voyeurism, and inciting others to have sex, quite often for her own pleasure. There's not that much to Naomi than that which makes her tedious as well as divisive. That said even though as many people dislike her as like her she does serve a purpose in respect to advancing the MC's sexual exploits albeit preposterously.
