Yeah, Ben Burtt. SO much talent, so many questionable decisions. I love his work overall, but there are things that just irritate me, too. It seem like hears something, then just latches onto it, like the warbling engines. I'm just glad he didn't go back and make every ship warble when they did the SEs. I would've been barfing in the aisles!
Or "the belches in Jedi aren't comical enough. Let's bump them up 30%." :p
On a positive note, I loved the IMAX movie "Special Effects", which he helped make. I wish I could see that again! I don't think it has ever been released in any format. And you rarely hear people talk about it, despite its important place in Star Wars history.
