The main issue with this movie at the moment is it’s story isn’t believable. We all know Hakeem only had eyes for Lisa in the original, there’s no way he smashed someone else.
To be fair, Akeem wasn't a virgin when he met Lisa.
In the first movie, it was implied that Akeem has smashed many of the bathers.
It isn't unlikely that he was smashing women other than Lisa in America. Also, Akeem was the type that would let a woman practically rape him due to being too polite to stop them. Remember the St. John's game where Patrice gave Akeem a handjob to completion under his jacket while he was sitting right next to Lisa.
The issue I have a problem with is the time frame. The movie barely left any gaps for when this could've happened.
Consider this. After the part where Akeem and Semmi were going on the dates in the club, Semmi says to the barber "we've been to
every bar in Queens"
That means they went to many bars off screen other than that one nightclub.
And that was all
before he met Lisa.
So, it is very possible that he impregnated a woman out there.
