All I knew about it was its tagline (besides its IMDb Rating) before going for it.
Tagline: On November 13, 1974, Karen Silkwood, an employee of a nuclear facility, left to meet with a reporter from the New York Times. She never got there.
I misinterpreted "She never got there." as "She went missing." What I thought would be the beginning of the movie was the end of the movie!!! And it was quite a job to sit all through to the end. The wikipedia page on Karen Silkwood was rather more interesting (especially the last para under 'Estate of Karen Silkwood v. Kerr-McGee' section. Talk about conspiracy theories!!!) than the movie (something that I also felt about 'The Elephant Man', but 'The Elephant Man' was still better than this... way better). No, I wasn't looking for big time action with blasts & explosions (mind you that 'North Country', one of my favorites, didn't have much action either) that I ended up being disappointed. But I wasn't looking for such a slow & dull story-telling either.
The performances by almost everyone, specifically Meryl Streep & Kurt Russell, were great but not enough to save me from the ample amount of boredom that the movie tends to generate.
