Coollector Movie Database is the only program to combine a personalized movie database with a video collection manager. The closest programs are just video collection managers.
To begin with, the program includes a huge encyclopedia of 92,000 movies and series. Because it's installed on your computer, you can use it even when you're offline. The interface is very easy to use. You can customize the layout to your liking, and make almost any search you can think of.
Then, you'll start personalizing the database. You can rate all the movies that you've seen, to remember whether they were good or bad. You can maintain a wishlist with all the movies that you'd like to watch. You can organize your video collection, remembering what you own, where it's stored, and what you've loaned to whom. You'll soon appreciate that the movie database is personalized. Indeed, your owned movies are now highlighted, and colored icons will instantly remind you of how much you like a movie or a person.
