It seems like it's even 'controversial' amongst Coen fans, some love it and some don't. I'm definitely in the camp that loves it but it isn't as funny as many of their movies (though it's certainly got laughs). While it was mostly ignored, I think time will be very kind to it.
I'll pick up Inside Llewyn Davis this week. It was probably the best Coen brothers movie since Fargo and was criminally ignored by the Academy (it was better than nearly every movie nominated for Best Picture).
Thanks for the prices, Mike! :)
