I saw this with my 6 yr old the other day (he's just getting into these types of movies).
This was by far the worst of the series. (although I don't remember much about JP3, so I will have to re-watch).
I'll admit I was entertained, so I didn't hate it, but lets be honest, This one makes the last one look like a Best Picture winner. It makes no sense whatsoever, The same characters keep making ridiculous stupid decisions. Then the bad guys, terrible, but then I thought about it. We have Trump as the president, so while they were terrible, I guess it was realistic in a sense.
Anyway, I always like these types of movies, so I'll keep paying. LOL..
