Alternative Character Interpretation: Is Andi a level-headed, self-controlled and realistic girl who fights off irresponsible parents, a creep best friend (Vik), the worstest slut ever and an awkward parasite (Bridget) or an irrational, hateful Entitled Bastard who continuously demeans her enthusiastic, sane parents, her Nice Guy boy tool, a woman with deep psychological issues who gets constantly slut-shamed instead of getting the help she deserves and a wonderful Good Bad GirlBig Beautiful Woman? Or, is she just a typical if exaggerated moody, insecure, self-centred teenager who is nonetheless somewhat sympathetic as she is repeatedly caught up in events she has little to no control over, ranging from relocating to a new town to falling for a Cosmic HorrorBecause Destiny Says So to being embroiled in crazed plots to destroy the entire universe.
Badass Decay: Cthulhu. The whole point of the book is that he sacrifices everything he wanted for Andi. He hates himself and her for it, and despises her enough to judge her unworthy of choosing even for herself as a result, but he still sticks to it.
Basically, Team Riley and Team Vik battle about who Andi should choose between troubled, self-loathing and controlling, but strong and loving Riley, and sweet and loving but troubled and self-loathing Vik. The latter are also attacked by Scarlett Samosa shippers, who found the abusive but passionate Vik/Scarlett more interesting than anything else in the book. Then, of course are the two stupidest minorities: Riley/Andi/Azathoth-in-a-murderous-and-humanitarian-phrenzy and hatefans.
Reviews are split between those who know the backstory to this series and those who do not. Amongst those who do know, it's split again over how successful a parody it actually is or whether it just comes off as simply another Twilight rip-off, albeit one with a more humorous and self-aware tone, and basically So Okay, It's Average (though the self-confessed inexperience of the authors explains that somewhat). Since the series invokes Poe's Law it inevitably risks accidentally inverting it, coming across as too straight (or, depending on your tastes, simply not that funny).
There are a few who think the whole project is more than a little mean-spirited, given that it's as least partially about tricking people who like Twilight-esque novels into buying a book that is supposed to parody everything they like. In other words, intentionally or not, it can come across as making fun of not only a genre but anyone who likes said genre (and now that it's published, making money off of them). Even some fans of the project think that stuff like giving the fictional author an actual backstory (and fictional family), Facebook page, and her own blog might be taking things a bit too far.
Ensemble Dark Horse: Uncle Neil is very popular thanks to his extensive backstory which we only get the barest hints of.
Older Than They Think: When brainstorming the series on their vlogs, they intentionally tried to come up with the most absurd concept possible. They then ended up with a less comedic take on Haiyore! Nyarko-san.
One-Scene Wonder: More like three-scene wonder, but the general consensus was that Uncle Neil needs to be in the book more.
Some people think it's this for Twilight, for those who think it is a parody. It is, of course, indeed an actual and intentional parody, but it exaggerates the negative points of the Edward / Bella relationship—Edward, for instance, never killed people for playing cruel pranks on Bella, never mind ate their souls or drove to insanity those who tried to harm her, while Riley does all three without reservation; Riley is also arguably even more of a stalker than Edward was, and belittles Andi's frail, human weaknesses less because of how dangerous being around him could be and more for how utterly pathetic he thinks humans in general actually are—indeed, he explicitly would Kill 'Em All if Andi wasn't around. The fact that the series has world-threatening stakes for their relationship (which actually is destined love here) may also undermine the point of what turned people off of the Edward / Bella relationship in the first place—the fact that Bella chose to pursue a romantic relationship with a damaged and dangerous stalker-monster, and exaggerating how dreadful not being with him was; for Andi, not being with Riley could bring about Armageddon, and breaking up with a vampire is likely easier than breaking up with an amoral alien god.
There is the argument that it comes across more as a parody of the Lovecraft-saga than the Twilight saga, since the authors rest the Twilight comedy mostly on how ridiculous they find the premise of their story in the first place—that is, they basically just rewrote Twilight, with some mild exaggerations and self-referential humour; while the Lovecraft comedy comes from things like actually turning characters like Nyarlathotep and Cthulhu into comedic human-ish characters. That it's partially written and marketed as a straightTwilight rip-off means that some of the parody is intentionally downplayed as well.
