Other than the fact I absolutely hate the Brady Bunch, I'd tend to agree. But the storyline was much, MUCH stronger in the second one, and they treated it like an actual movie, and not just dumb parodies of the cliches and conventions of the show for a full 90 minutes. But at least (in both movies) they didn't go the Underdog/Inspector Gadget route and use a real dog. That would have been tragic.
Oh... the new show. I just saw it on YT as well. And I was absolutely amazed. The writing is a lot more grown up... almost serious. Much better than the last series, which just tried to copy both the movie and the original series at the same time, yet utilizing the same structure. There is no running around with bubble gum music here. They seem to take a cue from those hundreds of CSI/Law and Order-y shows... but they do it like a million times better. And it seems they're going to have story arcs. or at least one really big one. And Scooby isn't on the screen 24/7. We actually focus on the other characters for a change. And they've given them depth too. They turned essentially a comedy into an action show with comedic undertones. And I'm loving that they made Velma and Shaggy a couple, especially Shaggy's reluctant reaction to it.
