If you're talking about the box, understandable. If you're talking about actual mac and cheese, maybe you just don't know anyone who knows how to cook.
Well, I mean, I can think of several different variations of a stovetop version (bechamel, the sodium citrate, or the condensed milk version that's been gaining popularity), a question of whether to bake it or not, endless add-ins, choices of cheese to use, choice of pasta to use. Making a bechamel without lumps is not hard but it does require some knowledge of basic technique. And it is actually conceivable that someone would use fresh pasta, which is a whole different ballgame. So while macaroni and cheese in its most basic is not at all a difficult dish it leaves tons of room for putting a personal spin on it...which means it has plenty of ways it can go wrong, too. I've certainly had plenty of disappointing mac and cheese in my life, sometimes at restaurants that really should be able to do better.
Yeah? Fancy baked mac and cheese isn't uncommon at all, sometimes dressed up with stuff like lobster and truffle oil, or sometimes as some sort of baked Wisconsin three cheese deal with crispy bread crumbs. Or it's a staple side at BBQ restaurants, and a lot of people people will judge a place harshly on its quality. I've also seen a lot of fried mac and cheese wedges on pub menus (which I do not recommend, just fill your wedges with cheese instead, the extra carbs add nothing).
Go to Applebee's and order Four-Cheese Mac & Cheese with honey pepper chicken tenders. The chicken tenders are excellent but the Mac and Cheese is the most watery garbage I've ever eaten. Then you will understand the true skill of making delicious Mac and Cheese.
You'd be surprised
There is a definite difference between Mac and cheese from someone who can cook vs someone who can't
Ofcourse you can mess up the basic like the milk and butter ratio and for more advanced stuff you can always have add ins like more cheese or some seasoning
Hell have you ever had Mac and cheese with some caramelized onions. Idk if I'm crazy for that but damn it's good
