I've still not caught up with this version, but I love the original version of Walter Mitty (starring the great Danny Kaye, from 1947).

Also, I agree that checking Rotten Tomatoes is a terrible habit. Here's why I dislike film review aggregator sites: If you get a genuinely divisive film - think The Tree of Life, or anything by Darren Aronofsky, which are love it or hate it experiences - they will end up with an average score. Whatever else films of that kind may be, whether you love or hate them, they are certainly not average. That's why aggregators are absurd, and should be completely disregarded.
