These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Olympus Has Fallen
Ho Yay: There are some vibes of this between Banning and Asher, especially Banning acting like a second father to Conner and Asher essentially playing the role of McClane's wife from Die Hard complete with Banning's rescue redeeming himself in the president's eyes!
Hollywood Tactics: The guys defending the White House heavily employ these. They refuse to take cover, trying to gun down who-knows-how many assailants while standing in an open field (OK, maybe you cannot run to cover, but there's no reason not to crouch or go prone). Even worse, the couple dozen guys inside the house keep rushing out the front door with gun blazing to be shot down by the attackers. No wonder the terrorists can overtake the White House in just 13 minutes.
Narm: The Secretary of Defense pledging allegiance to the flag. Yes, it's supposed to show how she's Defiant to the End, but the way she's wailing it while being dragged off by the hair reeks of this.
Special Effects Failure: A disconcerting amount of the CGI (especially the anti-air missile battery on top of the White House when it fires at the C-130) is about a decade out of date.
