Still packs punch.
The plot and acting get over some fairing basic action scenes.
The best scenes involve Jack Lemmon. Corporate greed and politics are slightly overdone, but the human aspects ring true.
This is from a period in the 1970s when environmentalists lobbied against nuclear energy. Now that big oil is the devil, it seems incredibly dated. It makes a fairly comprehensive case, though what is most startling now is how steampunk the technology is! Those combustion chambers and cooling networks look like they were designed to wobble loose... as they inevitably do!
In 1979 this seized the zeitgeist after the near miss at Three Mile Island. Now, the complacency of wealthy corporations by-passing safety measures still resonates, but the message has mostly expired. So this is just another Hollywood thriller... and an endearing memento from the decade when fashion got lost. It looks horrible, including the very austere photography.
Jane Fonda plays an ambitious reporter reluctantly presenting lifestyle fluff on a Los Angeles tv news station... while silently tolerating the ubiquitous sexism. When she interviews the head of publicity at a nuclear power plant, it's clear that in the background something is going very wrong. Jack Lemmon is the loyal company man who threatens to blow the whistle.
He's the main reason to watch; back then he portrayed the careworn, midlife American wage slave better than anyone. Eventually it loses credibility when he takes over operations at gunpoint, but there is an impression of a nation in decline evident in many '70s Hollywood films which feels very much like now. And it's fun to see Wilfred Brimley in the Homer Simpson role!
