Emma on Watch Instantly. I had enjoyed it tremendously in the theaters when it came out, and really enjoyed it again on second viewing.
I had also loved the Austen novel when I was in high school, and it's my favorite book of hers.
The story is a light one, a romantic comedy of manners, with a charming and sweet, but in some crucial ways unaware, heroine at the center. Gwynyth Paltrow did a great job in the title role, and overall the movie was completely charming.
