My last semester at Union, I audited Roger Haight’s seminar on Edward Schillebeeckx — when Haight was still allowed to teach. It was quite good, but really, if you aren’t going to read Schillebeeckx anytime soon, or don’t know how to even pronounce his name, watch the much shorter video:

I even know less about Haight than Schillebeeckx! I did, however, find this discusson regarding Haight’s run-in with the Vatican helpful.
Yeah, if you want to understand Haight, know what he thinks about Schillebeeckx.
