I watch almost anything SF. Lapsis disappointed me on several levels. Basically it is a story about pyramid selling. You're probably familiar with the idea: money isn't made by honestly selling a product, but instead, by recruiting an ever growing number of other "sales people" who are required to first buy stock before they join. Amway, Swipe. many others work like this.
The star wants to buy expensive treatment for his brother's chronic fatigue condition but the viewer can easily conclude that his brother is a useless layabout. This makes me think the star is a simpleton. Then he gets sucked into a pyramid selling scheme based on cabling optical fibre.
For me, this was the worst, most stupid part, because I used to be a project manager in a fibre optic comms company. And the tech aspects were just complete and total nonsense. I will spare you the details. So for me, the "McGuffin" was nonsensical and didn't work.
The acting was quite decent so I managed to watch it to the end and ... it just faded away.
