I liked it
It is a good film. I was not completely sold with Nicole Kidman as Lucille Ball, but she did a good job. Javier Bardem was brilliant.
I love period pieces, and Aaron Sorkin did a good job with this film. His schtick of back and forth quick cuts of characters debating/arguing is annoying, but the rest of the film was well executed.
I plan to watch I Love Lucy in future, and this was a nice forerunner/warm-up.
