This may be autism, but I don't like most depictions of dragons in media because they never seem to depict them like older myths and stories. To me, a dragon is an intelligent and horrible monster, it's strong and can raze cities but a particularly strong adventurer or party could kill it. Every dragon is a unique creation, has a name and appearance for itself. They're less a species and more like particularly evil "things".
I prefer dragons to be like that, similar to their depictions in old stories or in JRRT's works. Ancalagon the Black, Glaurung, Fafnir, the dragon from Beowulf are all examples of these evil beasts that are less a species and more monsters spawned from some dark pit or otherwise uniquely created. They're intelligent but they have no ambitions beyond greed and destruction, they don't make tax policies or rule kingdoms or anything. Just kill and hoard, and when they die the tale is remembered as a unique adventure instead of "you killed a white dragon of moderate age, we'll buy the scales for 100 kromer".

A lot of settings now make dragons either too strong or too normal. That's just a "red dragon", one of many red dragons, or alternatively dragons are mega strong demigods who can cast spells with ease. To me this detracts from the appeal of a dragon as an ultimate monster, because it's either reduced to another species of monster or is an obnoxious god who rules over people.
