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.
When asked during an interview whether his wife was bothered by him sitting there watching Jamie Lee Curtis strip, Arnold said that she asked him about it and he assured her "Honey, I hated every hour of it!"
Ending Fatigue: We have the awesome chase scene on the Forida Keys Highway with the amazing last second save of Helen, they kiss, roll cred.....Wait, the bad guys have somehow kidnapped the daughter and we have an awesome final battle, roll cred......Wait, it's a year later and we have a little epilogue, roll cred......wait Helen's now a spy and they're at an awesome party like the one at the beginning roll cred......Wait, it's Bill Paxton! Let's make fun of him again. The Tango!.........Roll Credits, whew!
Foe Yay: Harry Tasker and Juno Skinner. While in his spy persona, he seduces her with a very sexual tango while dodging detection from the bad guys, before either of them knew who the other really was. When they both learn of each other's identities, there is an amount of one-sided Foe Yay from Juno towards Harry, including alleging that they had a affair and kissing him in front of his wife Helen to hurt her.
Halfway Plot Switch: Sort of. We go from a standard spy story. Then abruptly switch to Harry's concern about Helen's alleged affair. They handwave the enormous concern about a massive terrorist plot, then focus on His attempts to win her back, then right back to the spy story, but with her involved now.
Unfortunate Implications: Siskel and Ebert were among those who became quite uncomfortable with Harry's manipulations of Helen during the entire middle portion of the film, all of which are played for laughs.
Visual Effects of Awesome: The fight at the Florida Keys and the climactic battle, achieved using a life-sized mockup of the Harrier jet mounted on a gimbal rig.
During some parts of the Florida Keys battle, actual Harrier jets (piloted by United States Marine Corps aviators) were used. The US Government supplied three Marine Harriers and their pilots for a fee of $100,736 ($2,410 per hour).
What Do You Mean, It's Not for Kids?: The video game. Normally bad guys fall down in a pool of blood but they (and Harry) can be blown apart, fly back with a shotgun, burnt alive, suicide bombers leave their bloodied ribcage on death and being hit by a train results in a bloody smear.
