An alien civilisation makes a series of contacts with life on Earth; one provokes a space mission. Still-extraordinary piece of mainstream SF with philosophical ambitions, plus a technical marvel. Essential viewing, even if it remains impenetrable to some.
Weather control satellites are interfered with to cause global destruction as part of a conspiracy. Longtime Roland Emmerich cohort Dean Devlin pastiches the RE formula, but hasn’t the same panache; this is a lumpy blockbuster that makes little sense.
Another perspective required? Here’s Xussia’s take.
A space station tasked with saving the Earth from energy crisis is transported to a parallel dimension. Good-looking, well-cast, but dumb-as-rocks sidequel to Cloverfield / 10 Cloverfield Lane that steals indiscriminately (Gravity to Evil Dead II) but can’t settle in terms of tone or logic.
