Coming from a background where these men are highly respected, thus being familiar with their style and works, this video simply doesn't surprise me. They're not being vindictive in saying that Orthodoxy has no theology, but instead being ignorant; because Orthodoxy doesn't look like what they're used to, then Orthodoxy can have no theology.
As for the sermon issue, only once have I attended a service where a homily wasn't presented. Ironically enough, it was at the Cathedral in Wichita, KS. There was some reason behind it, though I don't remember now what it was.
But truth be told - and I've said this elsewhere on this board - I've heard more theology, Scripture, and Gospel-teaching in one liturgical service than I did in ten years of exegetical teachings at a Baptist church. Even now on the occasion I visit a Baptist church - churches that pride themselves in bringing theology and exegetical teaching in all their sermons - it just seems empty compared to Orthodox services.
