Truly unpopular opinion:
Critics, as a group, across the overall body of their work, are typically correct. They consume a lot more of any given media than the general public does, by virtue of the fact that they're consuming it during those eight hours a day that everyone else is doing something else for work. As a result, they are tuned into a lot of the detail than the general public won't spot and know context that many people won't, like when a work is responding to a sometimes obscure other work.
A lot of critics in the internet era are pretty terrible and think that just recapping every moment of a work is somehow criticism. (It's not.)
But even so, most of them get it right most of the time. Most Rotten Tomatoes top critic Tomatometers are pretty good guides to what's going to be a good work. My wife and I, for instance, went in blind to watch Ex Machina and What We Do in the Shadows, both of which had about a 99% rating at the time we rented them, and were completely blown away.
Having said all that, the aggregate of critics' opinions doesn't necessarily mean you will or won't like a work. And you can like "bad" works -- which we all do -- without shame. (I just rewatched Bakshi's "Wizards" while making dinner the other night and it doesn't hold up. I love it anyway.) It's not a negative reflection on you if you like something the critics don't, and you absolutely don't need to get angry and defensive when that happens. Just enjoy your thing.
I think its less that they're incorrect and more that some often don't engage with a given work on its terms, and instead impose expectations on it separate from what it intends to do.
While not as often obvious as this, it is a lot like complaining when a Comedy is funny and doesn't try to be anything else. It'd be like saying Blazing Saddles or Young Frankenstein wasted Gene Wilder because they didn't give him a gritty character drama to chew on in the middle of absurdist comedy.
