Pretty Good,
First 2 episodes touch ground pretty well, it's not an amazing cartoon, but it's definitely better than I expected, most people who argue it's not a good use of the "Scooby-Doo" franchise probably haven't watched it since the 90s, last shows are way more lazy writing because it's for children, after 30 years, the scope needs a tweak.
My opinion may be biased because I'm not a dog person tho.
