how long did it take for Invasion USA to stop being morally bankrupt and irredeemably stupid, and start being hilarious? I ask because whenever that particular sell by date occurs, then I can issue a recommendation for London Has Fallen, which is even stupider, crasser, and somehow more violent then its already notably lunkheaded predecessor. Its also a significantly better action movie, with some more comprehensible (and just more in general) action versus its prequel.
Its also seemingly daring the audience to hate its protagonist, who crosses the line from 'steely badass' to 'lawful psychopath' well before the halfway mark. It brings back all the surviving cast of the first film, and then does absolutely nothing of note with most of them (Melissa Leo has her name on the poster for all of her maybe four lines of dialog). It handwaves away the issue of drone strike collateral damage while coming thisclose to being full on racist.
I'm too hardened to action movie absurdity to find any of this particularly galling, but your mileage may vary. If you're irony damaged like me, and can appreciate a well performed face stabbing or several you just might like this deranged, stupid, self-serious, irresponsible film. Or in about twenty years maybe it'll seem even funnier.
