The only good thing about it was the lengthy one-shot action sequence near the end.

I just watched the movie for shits and giggles in response to this thread and never saw a one-shot action sequence, so I checked your link.
Yeah...I'm just eyeballing this, but there are a ton of editing transition points in this sequence, at least 6 or 7. Any time the camera snaps 180 degrees or a character sweeps across the frame point blank they could be stitching in another section of the sequence. No reason to think it was a true one-shot.
Anyway, Olympus was a fun Die Hard clone. It knows what it is and has some pretty solid shootouts and a fairly technical duel. Bannon's a one man army power fantasy but Olympus tries to earn it somewhat, at least. He uses tactics, takes advantage of his knowledge of the White House, and is one brutal son of a bitch.
London on the other hand is like a cartoon version of Olympus, and Olympus was already a cartoon. Bannon has the two MI6 agents *leave* just as they see the fake terrorist Delta team is assaulting their safe house so that he and the President can take them on alone while MI6 finds a mole? Bannon is either treasonously incompetent or too self-aware of his own plot armor.
Everyone's talked about the racism and jingoism plenty, so I'll highlight that the SAS gets zero respect from this film. This SAS squad and its captain arrive on the scene to pull Bannon off a live terrorist he's interrogating, yelling "HE'S DONE! HE'S DONE! Back off, take it easy!" The enemy combatant is still conscious and unsecured, so the SAS captain just endangered Bannon and everyone else there...to what, allow the terrorist to die more slowly with dignity? C'mon now. The SAS are some of the most hardcore SOF in the world. They're famous for their brutal efficiency and black humor in the face of death. One of the first things I read about them as a little kid was an SAS soldier advocating emptying entire magazines into downed combatants because 100% ensuring they're dead and not capable of shooting someone in your team is more important than, like, any pretense about your own humanity. in London Has Fallen, though, it's constantly, "Bannon, ye can't do that, mate, that's crazy!" Did the writers mix up SAS with SaaS?
