I loved the Tom Wolfe novel (and most of his work, really), and I'm a big Jeff Daniels fan, so this was a no-brainer to watch.
I'm two eps in and it's really well done. Daniels captures Charlie Croker's huge personality and does a pretty passable south GA cracker accent.
The rest of the cast is solid:
sniveling Ray Peepgrass is nailed by Tom Pelphrey
Diane Lane as the first wife watching the downfall from the sidelines
Lucy Liu is Lane's best-friend
Josh Pais is the angel-investor getting wooed
Anthony Heald (the odious Frederick Chilton from Silence of the Lambs) is a heartless judge
Still plenty of time to fizzle or falter, but two eps in and I'm along for the full ride.
