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.
Anvilicious: A borderline case already. Definitely so had the director included the Coda included in the deleted scenes on the DVD.
Vincent and Eugene. That scene after Eugene gets drunk, anyone?
Eugene leaves him a lock of his hair.
One-Scene Wonder: Tony Shalhoub has a few minutes as the underground contact who brings Vincent and Jerome together, helping and lending the equipment necessary for the fraud, and is brilliant as a genetic profile "used car salesman".
In a few short years, scientists will have completed the Human Genome Project, the mapping of all the genes that make up a human being. We have now evolved to the point where we can direct our own evolution.
Had we acquired this knowledge sooner, the following people may never have been born;
On any given YouTube clip of the scene involving the twelve-fingered pianist, expect to find multiple comments that involve the phrase "Nark Nark". Ryan Dorin is in fact a professional concert pianist, among other things.
Designer Babies aren't necessarily bad. They have decreased chances of inheritable diseases.
It's not that the above necessarily wouldn't have been born, they just might not have those conditions which in many cases worsened their lives. Many other genetic conditions are fatal, so those without them would have a chance at life. True, it's possible having them in some cases is a trade-off (the well-known correlation Asperger's Syndrome and high intelligence, for instance), or merely through strengthening character, but one can't achieve much if they've died young from, say, progeria.
The reason Vincent couldn't be an astronaut. In the words of Cezary Jan Strusiewicz of Cracked: "If you have a condition that can kill you at any moment, common courtesy dictates you do not sneak into a profession where you're responsible for keeping a whole bunch of people alive. Whether it be here or on a super long flight through the cold, unfeeling vacuum of space. If Ethan slips away mid-flight to take a dump and his heart fails while he's sitting on the toilet, you've got a rocket ship full of future people that's going to smash into the nearest celestial body at about 15,000 miles per hour. There are some jobs you just shouldn't have, you selfish fuck."
