I have had many friends who graduated from St. Vlad's and I audited two classes of his. My impression was he wanted to give a shock factor and hyperbole to impress on his students the importance of the Scriptures. Sometimes, we list patristic works and we forget about the Scriptures completely, which does not bode well for Orthodoxy. So he will make harsh statements against Church fathers just so that he can take the seminarians back to basics of the Bible, and also because he does not like the arrogance of certain seminarians who think they know better and try to challenge his Orthodoxy.
He does have a Church father he loves: St. John Chrysostom. Last I remember he considers his exegesis much better than any other Church father he read, and he certainly does not have patience for Alexandrian allegorical methods. But that still does not give me the impression of some sort of heresy. As one close Coptic friend told me who is a Deacon in our Church, "you leave his class with a much better appreciation of using the Bible in all your teachings and studies." Despite his many controversial methods, if one can humbly take that from him, that says a lot as to why he is still teaching.
