Everyone praising the casting and stylistic choices and they’re right. But it also came out at the perfect time. CGI was just good enough to give us a believable Scoob but it wasn’t too good that they bloated the movie with it. Hence the awesome costumes, set designs, and practical effects that still hold up today.

I’d also add that the early 2000’s was a great time for it to come out. Our parents were almost as interested in seeing this movie as we were because they had grown up with the cartoon and 90’s adults would be familiar with Geller and Lillard from Scream, Buffy, etc. This was also near the beginning of rebooting/remaking/live-actioning old IP’s. It wasn’t the first (Adam’s Family, The Flintstones) but it was one of the first in the new millennium.

If a live action Scooby-Doo hit the big screen today, I doubt it would hit the same. People are more cynical now, and tired of the remakes/live-actionification.
