I hate to word things this way, but I can't avoid a true description even if it is unflattering. Hunt is in the category of rabid anti-Calvinists. For whatever reason(s) Hunt views Calvinists in an extremely bad light. His research is extremely poor and rushed. His sourcing has extreme problems (missing primary sources, misses the context of the quotes he provides/quote mining, biased secondary sourcing, failure to properly cite at times). He makes anachronistic historical arguments (e.g. Augustine was a RC). He has very poor exegetical skills.
I did read some of What Love Is This. I've read a journal article that points out the serious shortcoming of the book. I've read the debate book where James White and Hunt argue, and Hunt gets massacred exegetically.
In short, Hunt comes across as exceptionally caustic and hateful towards Calvinists, and his misrepresentations seem to be intentional at times. If you want to read non-Calvinist literature, Hunt is not a good example of non-Calvinist scholarship. So I would recommend reading something else.
