Angular has a few core concepts that are hidden by poor documentation and a lot of 'sugar'. For example, a "factory," "service," and "value" are just fancy implementations of a "provider." So, it's easy to get tripped up on the differences until you realize they're all the same thing. To me, the core utility of Angular is data-binding, directives, and dependency injection, everything else is icing on the cake but it makes it seem a lot more complex.
