If you read the comments, a lot of the hate is directed in many directions.
You have the "Ugh, woman" jerks, but then you have a different batch of "This just seems forced to appease feminists".
Then there's the:
- Confused about reboot, or sequel
- Not Funny
- Why is the lone black woman not a scientist and a stereotypical "sassy, black woman"
- Looks like Scooby Doo
- Tired of reboots
- Over Melissa McCarthy
It's very polarizing.
