While many of us know "Fargo" and "Big Lebowski", many fans still haven't heard of "Barton Fink", which is too bad. This is probably John Turturro's best role (and his least weird). Tony Shalhoub also gives an outstanding performance (at least as good as he was in "The Siege").
John Goodman? Heck, even he is pretty good here and I'm not a big fan of his (though the Coen Brothers do him justice like no others can). His portrayal of the questionable neighbor just really suits him.
There is supposed to be deep symbolism in this film -- some say it's an allegory for the rise of Nazism (and I can see that), while others say it's just a critique of Hollywood. I don't know. But, you know what? No matter what it's about, it's beautiful in a nihilistic way... and you will want to know: what's in the box? And I'm not going to tell you.
