Movies is another movie related app for the iPhone that offers you a lot of options in one package. That app has pretty much everything you need to make it the must have movie app without really losing any features that the other apps of it's type have.
Movies covers movies in theater and on DVD as well, giving you plenty of options as to what you can look for. You can search through them by title, release date, or even popularity to give you a good idea of what you should be spending your hard earned cash on. This makes it very useful as well, considering there are plenty of times that the movies in theaters aren't as good as those on DVD.
When you select a specific movie, you're given some additional info. You'll get to see the title, a short description, some of the films cast and crew, a poster for the film, and in most cases, a trailer. You can also head over and find out exactly where that film is playing as well, if it's in theaters.
Movies really does knock all the competition out of the water when it comes to movie theater and show time apps. There really isn't any other reason to use the other apps over this one, as it even links to the rotten tomato page for each review. But it would be an absolutely perfect app if it showed that score as well, considering flixter.com is a little less well known.
