Good DRM can be as unintrusive as possible, but it cannot be as good as a non-DRM solution because it has additional requirements. It needs to check that you've paid for the content and therefore you must log in to use the service. It needs to enforce regional licensing restrictions, etc. See popcorn time vs netflix. Netflix is probably as usable as it can be given the requirements. But it's still not good enough.
