A rather unusual case in which the subject matter is more interesting than the subject himself!
Does that make sense?
His movies, for example, look interesting.
Listening to him talk about them, on the other hand, not so much....
I tuned in for Guillermo del Toro, and his interview was fine, but not enough to carry the balance.
I'd say that unless you're a fan of foreign horror (Italian horror, in particular), this dive is perhaps deeper than you'll like.
