This is a strange little film, and I think it only really popped up on my radar because of the stars: Alan Alda and Meryl Streep (both are great in general, obviously). The former also wrote this, and I don't think he did a terrible job - not as good as some of the episodes he wrote for M*A*S*H, but still okay, if flawed. But to whoever picked the title, I'm not sure why they went with The Seduction of Joe Tynan. That's not a good title.
The film's a political drama with some odd comedic beats at the most random of times. I guess it feels like it's about politicians being hypocritical and wild behind-the-scenes, all the while putting up a front, but if it's trying to be satirical, it definitely doesn't nail that tone. I think it also loses the thread a few times; any time it suddenly starts focusing on family drama, it feels very jarring.
Many of the individual scenes are good or entertaining on their own. The dialogue's generally good, and delivered well, with mostly strong performances. I think it's all put together in a very strange way though, that makes it feel messy, but that unpredictability and chaotic structure also makes it interesting in its own strange way.
The Seduction of Joe Tynan was only partially successful in seducing me as a viewer. It was interesting and kept my attention fairly well, but it was also kind of a mess.
