My only complaint is sometimes they are way more steps and more exspensive sets of ingredients than other recipes. But often it's worth it for vastly superior results.
That's why I liked Serious Eat's Food Lab where Kenji also breaks stuff down but in an accessible set of recipes. Similar to Alton Brown's Good Eats, also a great resource if you like understanding the chemistry going on in your cooking!
A lot of recipes you find online are really guestimates on the amounts, so you never get the same result as the author. People are very bad about guestimating volumes, like "about 2 tablespoons of oil" when they really used half a cup.
Or high-heat nonstick cooking with like one teaspoon of oil in the pan, heating it to nigh-smoke before adding anything else. LOL. Or steel or cast-iron temp + fat combos that make no sense and are guaranteed to give you a bad time. Either lots and lots of recipes are nonsense on this front, requiring modification of one form or another to be reasonable, or these people have magical pans that I do not.
