It's pretty easy to learn, has simple features that are powerful but not overwhelming in terms of options or user interface.
I like how it can be customized with themes and skins so you don't have to stick to the basic look if you want something slightly different. The only thing about the free version would be more customizable plugins/extensions, perhaps an option within settings to pay extra for premium? There isn't anything I dislike at this point besides nothing really new (aside from maybe price). With its ease of use, it allows me as a beginner to edit videos without having to rely heavily on other people who know what they're doing.
