With DRM someone is keeping your video and worse, the code running on your computer, secret from you. If it has bugs, you can't fix them. So no, I'm afraid all DRM really is bad.
Yet, Netflix open sources the code[1].

DRM is evil. DRM is not made for the user but for companies that tries to protect an outdated business model. DRM is certainly a technology that should never make it to the HTML5 standard.
You write that not all DRM is bad. Can you come up with an example where DRM is "not bad"? I can come up with plenty of bad examples that hurts legit users more than the users that finds their way around the DRM.
Whereas with EME you'll have to license PlayReady and Widevine and maybe FairPlay.
