Agree. Arguably the worst movie ever made. Meatballs II is close though.
Ramis and Aykroyd had a script in their back pocket for decades.
But Harold Ramis and Bill Murray had a falling out over Groundhog Day, and didn't want to work with each other ever again.
Ramis died earlier this year, and at the Academy Awards, Murray did an ad-lib shout out to him.
So maybe they could have gotten it done.
Honestly I didn't really like GBII that much, so maybe it's just as well.
