Forgettable but entertaining. Mitchell likes his romantic comedies to have meat & bones and maybe Morning Glory was the experiment that paved way for some of his most interesting works. The script deserved a bit more development because you can feel it wants to be deeper than that, but it still works. Then we have Rachel McAdams overdoing it while the rest of the cast pushed some serious autopilot buttons.
I think its actually a simple and fun movie. Performances are good,story so-so but still interesting (its like "The Devil Wears Prada" in broadcasting environment) and I like this kind of career-fighting movie.
In Broadcast News, we sympathized with Holly Hunter's drive to maintain the respectability of the nightly news. Now, 25 years later, we're supposed to sympathize with Rachel McAdams' attempts to turn a respected newsman into a buffoon and bring the standards of a morning show as low as they can possibly go. Still, mildly entertaining if you don't think about it.
Not as deep as other films about television but the performances are what make this film a step above most commercial comedies in the past few years. Best low key comedic performance by Ford since the Indy movies.
