The China Syndrome (1979)

I wanted to really like this film. There are a lot of strong supporting performances (especially Peter Donat as Jane Fonda's skeezy boss; there is an incredibly uncomfortable scene at a party that he absolutely nails), the chemistry between Fonda and Douglas is believable (if not at the level Douglas later achieves with Kathleen Turner in Romancing the Stone), and Jack Lemmon gives a tremendous performance during the "event" that spurs the action through the rest of the film, and again during his first interview with Fonda at the bar. Unfortunately, the second half of the movie starts to get more "dramatic" and the performances increasingly shallow/ham-handed until Fonda's final monologue.
