To be blunt, Morning Glory was a waste of time. I can't say much good about it. If you've seen the trailer, you've seen anything that might constitute a high point.
However, let's give some thought to this film nevertheless. My thought arose from the premise of the film that the character played (really, over-played) by Harrison Ford should lighten up and get into the froth of morning TV. He is portrayed as a pompous former anchorman who wants to do "real" news. During the course of the film, our heroine, young, perky, and determined Rachel McAdams transforms by show by various antics: an anchor kissing a frog, the weatherman televised on a roller-coaster, and other inanities. And the only "real" news that occurs in this endless film comes when the sitting governor is confronted with criminal charges right before the cops show up to arrest him. This isn't news, it's a spectacle of humiliation (even if he is guilty, which no one is assumed to care about after viewing the bust). Television news becomes more and more of a wasteland all the time from what I can see (which is as little as possible beyond the Daily Show and the Colbert Report). But as much as one naturally pulls for Rachel McAdams to succeed, I kept thinking that success isn't worth it. What have you done? She gets the guy in the end, but by the end, your really don't care.
My review mixes two types of criticism, bad movie-making and bad journalism, but if you choose to go, you're forewarned.
