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: The Transporter
Anti-Climax Boss: Lola in the second film. You'd expect her to give a better fight but Frank dispatches her quite easily.
Cargo Ship: In 2 after Frank demolishes a garage-full of mooks, the Jamaican cab driver Frank used to get there is seen speaking soothingly to the yellow Porsche he's hiding in. At the end of the movie we see he's nicked the car and turned it into a Porsche cab, to the envy of his fellow cabbies.
You just know this trope applies to Frank when no-one's looking.
Evil Is Sexy: Lola, so much. Assuming that you aren't turned off by how creepy she is.
Ham and Cheese: Kate Nauta in The Transporter 2. It's pretty clear from her line delivery and facial expressions that once she read the script (which calls for her character, Lola, to spend half her screentime wearing a soaking-wet negligee, disheveled hair and runny eye makeup while dual-wielding pistols and gunning down all manner of individuals), she decided to take it as far as she could, and she looks to be the only person not to deliver the cornball material in a serious manner.
Ho Yay: Some fans find homosexual imagery in the films:
Frank sucks the last breath out of a dead man's lungs to stay underwater and evade the villains' gunfire.
Frank covers himself in motor oil to fight a gang of Mooks, and one of them almost slides head-first into his crotch.
Every movie has a male villain who physically touches Frank when talking with him.
(From the series): Frank and Jim in episode 2.
Moment Of Awesome: Pretty much all of the fights form the first movie, the bus station one in particular. In the second movie, he kills eleven Mooks with a firehose! Dry firehose, by the way.
How about how Frank turns the tables on the Big Bad in part 3 with the exploding bracelet?
Sequelitis: While some people will argue that the second film is just as good as (if not better than) the first one, wihle the third film does have it's moments, most people say it's not up to par with the first two.
The Scrappy: Valentina from the third movie. She's easy on the eyes, surrounded by a black and gray cast, in a franchise with over-the-top villains and character flaws, and is supposed to be sympathetic. Standing out as obnoxious under those circumstances is something of an accomplishment.
What an Idiot: Johnson's inevitable death scene in the third movie. Frank attaches the exploding bracelet to him, him to the car, and drops the whole package off the back of a moving train (long story). Instead of doing the sensible thing (remaining attached to the car, landing on the tracks, living) Johnson detaches himself from the car, remains in the train, and is promptly blown the hell up when the car is too far away.
Johnson probably didn't want to got to jail, so he decided it would be better to take Frank and Valentina with him by blowing himself up. The look on his face 1 second before the bracelet detonates says it all.
