Seems to me they're more reaching for an older demographic while still having enough kiddie mentality to turn everything into narm. And incidentally, some of "What's New Scooby Doo!" and some of the movies, particularly "Scooby Doo and the Cyber Chase" did indicate rather strongly at a relationship between Daphne and Fred.
So far it seems to be quite in the opposite direction from the old ones. The old ones had really lazy style, but everything was fairly comfortable. However here, the characters are really rough (every single one of them is flanderized) while the art style is actually quite impressive (well, considering the property). I really liked the use of lighting in this week's episode, but Velma's really starting to scare me. The only good moment between the two was at the end of the second episode, which was also the most subtle the series has ever been.
At any rate, I think I have a pretty good idea of what kind of quality to expect from the series, and I wouldn't exactly recommend it. But I'll definitely be watching it anyway... because its scooby-doo (and curiousity from an artistic standpoint).
