I'm talking about the movie, Doubt, although the subject of doubt in general would be a good topic one day too, wouldn't it? Anyway, this new film with Merryl Streep and Philip Seymour Hoffman looks like a riot of fun to me. It's not a comedy and isn't supposed to be funny, but rather a serious, suspenseful drama.
I look at the 2 minute clip here -- http://www.usatoday.com/life/movies/news/2008-10-28-doubt_N.htm -- and I say, "Wow! I know people just like that! I've had conversations just like those two minutes! And so many issues got brought up in those two minutes!"
Naturally, there's a lot more to the film than those two minutes, but I'd say those two minutes look promising enough to me.
