@Lobster:
I wonder why they suddenly ended "Jackie Chan Adventures".
It was a great show. Although the plot did seem to be recycling itself.
They did air the remainder of the 5th season, but in like dead time, and only once, like six months after they started.
! Summary: that obnoxious Shendu's Son character manages to acquire all the element-demon powers he wanted, and his aim is to basically turn the world inside-out. With the usual comic fashion, both the main heroes and the main villians have to combine forces to take him down. In an amusing moment, Valmont makes a cameo as a bus driver, showing how completely he's fallen.
! I was most disappointed because Hak Foo didn't get his chance to be subservient to Shendu's son– considering his willingness to bow before every other arc villian in the series. '
Mind-blowingly, the free forum that used to discuss the series still exists, although all the old members (me included) have basically abandoned it.

there's a lot of discussion of the last season, you should be able to pick up anything you missed.
