Well... this was another sequel that no one asked for, at all and we can probably honestly say that this is a huge reason why it flopped.
I had absolutely no interest in seeing another sequel of MIB, especially one without Will Smith, and especially one that is gender-swapped and rests closer to the reboot mark than the remake mark.
Which are all reasons why I didn't see it until it came around for free.
And as predicted while all but rebooting the franchise, it also attempts to make a political statement with the jokes coming from "laugh because you agree with this" type of humor, which rarely actually lands. And as a result it feels like SNL doing MIB in a sequel no one asked for.
