Hopefully so. Ian Whyte is a capable actor it seems, but he has none of that caged animal two-seconds-from-snapping seething fury that Gregor needs IMO.
Gregor likely suffers from a brain tumor which is (at least in part) the cause of his enormous size. He suffers from constant near-debilitating headaches and takes enormous amounts of the narcotic "Milk of the poppy." So not only is he always mad because of constant pain, he is always high.
Since neither Conan Stephens nor Ian Whyte are as abnormally large as Gregor is supposed to be (Nearer 8 feet than 7) one can assume this version doesn't have Gigantism or any sort of variant of it, but to lose that "motivation" for Gregor to be the monster he is would be a shame.
