This movie was gonna be an absolute disaster regardless so doesn't really bother me they are going full-retard.
Honestly the only thing worse would have been an "original" cast reunion - anybody remember how awful GB2 was? And now without Ramis and most likely Murray and everyone else fat and in their 60s it would have been absolutely catastrophic. Akroyd has been trying to get that shitshow of the ground for years and I'm glad he either came to his senses or was told "no" by the moneymen.
One big plus of this casting decision means a complete and total end to the "Stern should make Ghostbusters!!!" talk.
