Yeah, The Brady Bunch Movie was great because they realized what made the series great to a modern audience: the retro feel and the simple wholesome morals and comedy and juxtaposed it with the real world. The Bradys' world didn't change at all. Their house and attitudes were stuck in a time warp. Even the exterior was a set just like the original series. But then they escape into the real world. Everything about them remains the same, but it allows the movie to poke fun at how different they are to everyone else. I particularly like the scene where Cindy's ball bounces into the Dittmeyers' yard, a clear example of the dividing lines between worlds, so to speak. On her side of the fence is the Brady yard set, but as soon as she steps through the gate, there's loud music (which wasn't at all audible before) and, look, we're actually outside!

Ah, I love that movie and its underrated sequel, A Very Brady Sequel.
