Is the plot of Savers underrated? It gets written off as a dumb fun action show (and it sort of is), but the setup has way less childlike wonder.
The Digital World is treated less like a fantasy adventure and more like a sovereign country that humans have to meditate with. DATS is there trying to keep the peace between the dimensions and monitor threats. They are like the Hypnos, but instead of deleting rogue Digimon, they ship them back home (hence the name "Savers"). Until Kurata decides to wipe them all out, and forces Yggdrasil to declare war on all humanity in retaliation. It's the first time we see the Royal Knights as a proper organization guarding Digimon's interests (Sleipmon watching over DATS for the entire show was pretty cool).
