I didn't even watch the trailer and I already know that it's bad. Part of the big problem is that it seems it's already alienated the mainstream viewing audience and won't really attract the SJW types because there's going to still be things wrong with it.
Secondly, while both films featured SNL talent, I've never heard of any of the actresses for the new film. While Aykroyd and Murray are instantly recognizable due to their long film careers (today), they were already recognizable in 1984. Hudson (Zeddemore) didn't have the star power as the other three, but Ramis (Spangler) had Animal House, Caddyshack, and National Lampoon's Vacation in his career (though only actually acted in one). Murray already headlined in Meatballs (co-written by Ramis) and was a minor character in Caddyshack. Aykroyd had The Blues Brothers and Trading Places.
On the other hand, we have the lead McCarthy, who has had Bridesmaids, Mike & Molly, and a few other smaller roles, Wiig with a few other roles (not many of which have been comedies), McKinnon and Jones, who have little to go in beyond sketch comedy and their minority statuses (McKinnon being a lesbian and Jones being an African American woman).
