I watched this a few weeks ago as well, and it is a very good, even-handed overview of systemd. He talks about the history and other tools that came before, like Apple's `launchd` and Ubuntu's `upstart`. He also talks about the actual problems with it, rather than the FUD hysteria (and also explains why some of them are FUD).

He's from the BSD world, so his POV is as an (mostly) outsider.
