DH used to be a big hero of mine.
Mine, too. I was uneasy with the vitriolic rhetoric and sloppy research found in The God-Makers. IMO the success of that book/film went to his head. What I found doubly odd was that, given the commercial success of The God-Makers, his follow-up projects didn't go after the Jehovah's Witnesses or another high-profile non-Christian organization. Instead, he directed his sights increasingly on fellow Christians with the books The Seduction of Christianity, Beyond Seduction, Whatever Happened To Heaven?, and now What Love Is This?. Each book alienated more and more of his prior readership, and saw smaller and smaller sales numbers as a result. I strongly suspect that What Love Is This? was written as a belated response to Calvinist writers Gary DeMar and Peter Leithart. In 1988, DeMar and Leithart wrote a rebuttal to "Dave Hunt's Theology of Cultural Surrender" in their book The Reduction of Christianity. They demonstrated that Hunt is far more accusing of non-dispensational, non-PreMil/PreTrib Christianity than the historic, orthodox creeds of the Christian Church are. In doing so, Hunt falsely sets himself up as the yardstick by which men's faiths must be measured.
Good thing Hunt hasn't quit his day job. It's always worthwhile to point out that Hunt has no formal theological/historical/seminary education whatsoever. In his day job, IIRC, he's a certified public accountant. If he were as careless with the facts and figures in his client's books as he is with his own, he'd lose his day job, too.
I fully expect Dave Hunt, at some point in the twilight of his career, to announce that he and his church are, alone, the last remaining faithful believers in Jesus Christ, here in the twenty-first century.
And on his deathbed, he'll probably express doubts about the other members of his church, too.
