Sure. I can give a few examples of ones better than what WotC produces.
First, I'm currently running "Glimmering Crypt of the Ioun King" by Planet X Games. It's a simple dungeon crawl - traps, combats, with enough of a background that it can be dropped into many campaigns. It's around 30 pages, for levels 6-8. You can tell that the writer was focused on this kind of adventure, and the theme is clear. It's a better dungeon than anything in Rime of the Frost Maiden.
Looking at a megadungeon, compare Dungeon of the Mad Mage with Barrowmaze, which comes with a town, NPCs, small "satellite" dungeons, a few compelling villains, traps, backstory.
Look at something like "Hole in the Oak" by Gavin Norman instead of some of the early level dungeons by WotC - and see how formatting and presentation can make something easier to run by new DMs.
