I hate knowing how much money is spent on them so that they can annoy us with every attempted second of our lives. What, you can't use that money to better pay your workers? You can't use that money to improve aspects of your company, so you're going to pay these groups of obnoxious pricks whose entire existence is to annoy people with your ads?
The ads themselves are too theatric for me to care, I can't tell you the amount of ads I've had to stomach hearing through Spotify that makes me care even less about a product. They just take turns outdoing themselves as to which ad is the dumber of the bunch that night. Even worse are the ads that try too hard to reach for something that was 'hip' to do like 5 or 10 years ago.
The lying in commercials. I've learned in life that some brands that aren't even the brand of choice, the best option available. I've been surprised on some of the things I've acquired from even dollar stores that somehow are better than the name brands.
And even then, there's still lies projected from commercials that attempt to snag you in for money.
The 100% fake enthusiasm, especially if it comes after buying a mediocre product.
The annoying corporate speak.
The bad voice over where lipsyncing is completely gone, this is mostly a thing of the past here in Sweden, but from time to time you get ads from companies launching a product across europe and only record one video to the ad and then translate and do a new voiceover for specific languages as needed, but fail to sync the audio with the video.
Annoying music, for months now a company has been pushing their financial services withe the same terrible ad that is a slideshow and an increadibly annoying music, there is no person talking, they just have a fast tempo music track. I have vowed to never buy anything from them because their ad sucks and is annoying.
Reusing ads, sometimes a company buys almost all ad slots on YT over months and reuse their one ad video so it is completely grating.
Self-righteousness, some ads go from being overly enthusiastic to being intolerably self-righteous. There was a new clinic chain of companies that started a big push a few years ago on yt and for several months you had to listen to an overly kind and happy grandmother wearing a company branded sweater, faking a hearty laugh and telling people to go to their clinic.
