It's the kind of movie that's perfectly enjoyable at face value. George Clooney's performance is note perfect, the kind of role at which he excels and it's hard to imagine anyone else playing it. The other performances are very strong. The script is touching at times and very funny, flirting with movie cliches but never giving into them. It's poignant as a letter to the many people who have been laid off in this economy, using real people at times talking about what it felt like to be fired. The film is stylish, the music is that sort of acoustic guitar that pulls at the heartstrings, etc.
The "movie lover's movie" bit comes because of how subtle and nuanced the film is. There are very slight motions that add unlimited depth to the story, a nod of the head here, a small smile there. There are lines that are funny, but, when examined more closely, provide a deeper look into the character's soul. One such line, "I type with purpose," seems to be a total throwaway line that got a couple of laughs, but I can't stop thinking about what it said about the character that delivered it. The camera work even changes subtly at one point to show a change in theme. It's the kind of movie one could watch two or three times and discover something new with each viewing. Go see it at least once. It will surely get nominated for Best Picture and Best Adapted Screenplay -- it's based on a book -- and Clooney will most likely get nominated for Best Actor.
A side note on the previews before the movie. There was a trailer for a movie starring Chris Rock, Martin Lawrence, and Tracy
