Empire is a venerable British movie magazine that has amassed quite a library of film reviews since it was first published more than 20 years ago. Their reviews tend to be aimed at the enthusiastic film buff, rather than academics. I have always found the reviews entertaining and a worthwhile read.
Now, the entire Empire archive has come to the iPhone and iPod touch with the Empire Movie Guide [iTunes link]. The US$4.99, 8.9 MB app puts all of the reviews on your phone without need for a data connection. As a nice bonus, Empire grabs the most recently published reviews over the air when you are connected and launch the app.
The Empire app contains about 9,000 reviews, searchable by actor, director, genre, writers, or release dates. Want to share the reviews with friends? Empire allows sharing via email, Facebook, and Twitter.
If a movie or soundtrack is available in the iTunes store, the review provides a purchase link. The Empire Movie Guide won't help you find movie times or locations, but it does put a library of well-written reviews in your hand.
