I watched ROTJ for the first time in years to contrast it beside Daneditor's re-edit. This was a little while ago.
Can't believe this never occurred to me before. The film would be much improved if the Ewok's noises alone were cut down. I wanted so badly for them to shut up. But I forced myself to listen so I could have an accurate feel for this film's quality.
Daneditor did a lot to help. Check it out some time.
