On the one hand, the science is… wonky. Environmental damage severe enough to push the population down to barely-sustainable levels and apparently kill all visible plant matter, and yet beeswax is plentiful enough for candles. Or else tallow, which is of course another word for ‘fat,’ which is not exactly something that you literally burn away in poor-nutrition environments. And they’re all dressed incredibly badly for folks able to root through six billion people’s worth of abandoned wealth.
On the other hand, Denzell Washington and Gary Oldman.
On the gripping hand, it’s just a movie.
