Dunno about that for Parasyte as Sentai needs a stellar dub on this and outsourcing doesn’t guarantee a stellar dub: Vancouver is mercurial (and untested with Sentai) and CA is only likely to yield the same results as an average Sentai dub.
IMO they need a proven ace director, one who has evoked great performances from noobs and veteran actors alike, and should call in Greenfield, Sentai’s semi-retired ace director, and treat it like “Gantz 2.0”.
I agree that the dub of Parasyte does present a problem as the majority of the best Sentai-era dubs were done by Foster and he’s been cashiered and male leads have been something of a stumbling block for Sentai dubs in general.
