Pro Needs no additional codecs
Everything MPV needs to play media files is contained within which means no outside codecs are needed.
Pro Minimal interface
The whole interface is just a video with a minimal OSD.
Con Lack of a typical GUI can be jarring to some
The minimal interface comes at the cost of beginner-friendliness. You need to know keyboard shortcuts by heart, settings are set in text files, right-clicking won't bring up a menu, etc.
