I agree that the video has a bit of an anti-open access bias. I think there are also crappy closed access journals too. Impact factors are not infallible and can be "gamed", but they provide a pretty quick clue about a journal's standing within its field, whether open access or not.

A better understanding of what peer review is and isn't would help the community when scientific results are taken from their specialised fields and publicised in the wider community.

I think the biggest problem in all of this is academic laziness and failure to apply critical thinking.
