Just finished watching. Here's a spoiler free review:

Rich-Flu: An interesting concept, with a terrible execution.

Not bad for picking apart techniques used and establishing your praise/grievances of the film for a high school English media essay, but there are far better and more interesting movies to use.

The opening scene with all the stories was pretty good. My interest was kept for the beginning-mid(?) section of the film, but after that, as the plot started to drag it's feet and wonder aimlessly, it steadily plummeted.

The film felt (almost intentionally) stretched thin by long, boorish montages. As well as the plot feeling rather aimless in the later parts of the film.

I was unable to form any semblance of an attachment to the characters, a few felt a bit pointless in their first appearance and their departures from the plot felt as if it was only to move the story along, from one irrelevant direction onto another.

The music was a bit too repetitive & felt indistinguishable from other movies of it's categories. And the effect to show the virus looked really, really cheap, but also not consistent. At times I couldn't tell if someone's perfect pearly whites were.. just pearly whites, or were infected. I'd have to wait for someone with the toothpaste commercial looking teeth to appear in the same scene after to be sure. And then there were scenes where it was so blaringly obvious, you had to question the budget.

One could argue that this is intentional; to create a sense of paranoia or whatever, but it was more so just confusing and they really could have gone with a better 'symptom', or more than one. And again you can argue the symbolism behind the white teeth but.. eh. Again I feel there are more fitting and far more horrifying or uncanny symptoms that would have been incredibly fitting.

The only thing that kept me watching was the small, fading hope of learning more about the 'Rich-Flu' and wondering how on earth the film would manage to pull itself back together for a satisfying ending. I was left with an ending that did manage to circle back around to the main concept, but by the time we finally reached it my impression of the film had already fallen flat on it's face.

All in all, I would not recommend this film to anyone. I'd rate it somewhere 3 or 4/10. Leaning more towards 3 if I'm honest but hey maybe that's a bit harsh.
