It's 10 episodes for the first series & I can't wait for the second.
Unless you know something I don't, there isn't going to be a second outing - it's a finite narrative-driven series, more akin to a six-part BBC drama than the usual bloated US stuff (and all the better for it, in my opinion.)
'Twas utterly superb, all the same. It managed the very neat trick of paying obvious homage to the film with every shot, every musical note, every bit of dialogue, but I never felt as though it was retreading old ground (though it came close a few times!) or watching something that was trading on old glories. Freeman was an inspired choice for the lead - his appealing 'hapless everyman' schtick making him a worthy sucsessor for William H. Macy - and Billy Bob Thornton was a class act all the way. Loved that chilling last scene where he just talks quietly at the cop and reduces the man to a nervous wreck!
Also very, very funny, albiet in the very darkest shade of black.
