disappointing magic

There are works like Harry Potter or The Lord of the Rings where fantasy is seen as something unique and special, but here... it's disappointing in several ways.
The clearest example is the fantasy species that, although they match the descriptions, are disappointing.

They currently remain anonymous because since firearms were created they are easy prey; it's mainly to maintain the magical culture, other than that... they're worthless.

Vampires: They are nocturnal, their eyes hurt in bright light, which is why their houses are always dark; hence the rumor that they burn in sunlight. Also, mirrors used to be made of silver, so they couldn't be seen in them, but now they can be seen with any mirror or camera. They drink blood, but nowadays an average person has more calories than three men from the medieval era; they only need one drink.

Werewolves: they turn into wolves... but they gain the mentality and intelligence of one; they are no smarter than a dog in that state.

Immortals: Many obtained eternal life by accident. It is believed that they lived through the most important events in the world, but no, they were very far removed from those events. If you ask them what it was like to meet Jesus, they will look at you strangely as if "Why would I know him? Did you know Michael Jackson?"
Dwarves: ... they're just dwarfs, and that's it; centuries ago they managed to say it's a human mutation.

Aliens: They exist, but they only come to visit as tourists, like the classic American who goes to other countries to see "their culture" and just takes stupid pictures. In fact, young aliens, when they are partying with their friends, come and steal cows just for laughs.

Damn it: they became lawyers, just as vile and deceitful, but this time in suits

Fairies: They make pranks on YouTube about accidents; if you fell in a funny way and it was posted online, rest assured that a fairy pushed you and uploaded the video.

Oracles and Prophets:
Women and men who entered a trance to see the future sent by the gods.
Currently: The fortune-telling business went bankrupt because of Google's algorithm. These days, they work writing fortune cookies in Chinese food factories or compiling weekly horoscopes for gossip magazines. They're so bored with predicting the future that they spend their time spoiling football matches and Marvel movies on Twitter just to annoy people.

Ghosts: People believe they remain in this world to solve mysterious murders or close tragic cycles.
Nowadays: Ghosts don't go to the afterlife simply because they left ridiculously mundane things unfinished. A ghost haunts a house because it died halfway through a Netflix series and doesn't want to leave without knowing the ending, or because it left the oven on and its anxiety won't let it rest. The only way to exorcise them isn't with holy water, but by finishing their unfinished tasks or canceling their monthly subscriptions.

Elves: Ancient beings, tall, perfect and connected with nature.
Their reality: They're the typical insufferable types who promote the Goop lifestyle, extreme veganism, "window cleaning," and judge you for using commercial deodorant. They have absurdly expensive "sustainable" clothing brands and look down on you because they "remember how the Earth breathed before the Industrial Revolution."

Wizards and Sorcerers:
Forget throwing fireballs or teleporting. These days, magic is the equivalent of high school algebra: endless, boring formulas full of variables that, if you get one damn sign wrong, ruin the whole result.
Since technology has already solved the big problems (it's easier to light the stove than to calculate the thermodynamics of a fire spell), magic has been relegated to ridiculously specific and annoying spells.
Wizards no longer afflict you with plagues of locusts; they cast an "Asymmetry Spell," which makes your left sock always roll down inside your shoe, or the "Eyelash Spell," which makes you feel like you have something in your eye for a whole week even though there is nothing there.
Their social status: Nobody respects them. They're the typical weirdos who say things like, "Did you know that if I calculate the radius of the glass and the density of the alcohol, I can make your beer boil?" And people just ignore them and focus on other things.
