I personally think the whole "Everyone gather for a photo" ending (including Obi and Yoda), is a little more than campy and a very weak ending.
I truly think ROTJ should end with Vader's pyre; either a closeup of Luke's face or the behind-the-back distance shot. Cut to credits.
It's odd, the images of ROTJ's ending (hugs, ewoks, songs and ghosts) are so embedded in my brain as 'natural' but when I think about how campy and lame it is for such an epic series to conclude, I can't help but to hope an alternative ending scene is chosen.
