I like this widget. The little DVD spin at startup is a nice touch. It also seems to have some nice features. I like the DVD cover art as well.
A couple of things I would like to see added:
Add more review sites like IMDB as well as Amazon.
I am sure you are using Amazon's click through feature so that you get commissions to help pay for the widget and that is great but I like one button add to my Netflix Queue which only a site like IMDB.com offers. Plus I trust the reviews at IMDB more than Amazon's reviews.
I'd like to click on the title in your widget, be taken to IMDB.com for the review of the movie, peruse the review and click the big red NETFLIX button if I like it well enough to add to my Queue.
Also offering the ability to choose your sort order would be nice. Sort by release date, alphabetical, or movie rating would be nice as well.
All in all though still a very nice dashboard widget and a welcome addition to my dashboard.
