In brief, JP3 is solid popcorn entertainment. Everyone seems to throw around the opinion that 1) it has a sucky ending (I thought it was at least original, better than a retread of some tired idea), and 2) it has no character development (??? I'm convinced "character development" is the first phrase used by people who know nothing about film but want to sound like they do). Who expects character development in these films? It's a roller coaster ride. Do you go to Six Flags, get off the big nasty coasters and say "It was fun, but I expected more character development?" C'mon, people. Sit back and have fun. I did...a lot of it.
As for those who complain about (MINOR SPOILER) the lack of grief over a spouse's death, I just want to add that I don't remember the person ever referred to as a spouse...couldn't it have just been a boyfriend?
