Secret Life of Walter Mitty - 6.5/10
Oddly enough, where this movie really seems to fall on it's face is during Walter's daydreams. Too often played for laughs (Benjamin Button, why?) that never materialize, they really were over the top in a bad way. Which is too bad, because you would think those sequences would give us a better, closer look into the character, instead they went for flash over substance or cheap laughs. Without the daydram sequences I would rate this much higher.
Those sequences are the only parts related to original Thurber's story.
And I absolutely agree that they should've left that concept on the cutting room floor since it was used properly only once and then completely forgotten.
