As I've made abundantly clear (in fact, it's turning into my MO!) this part of the film is my least favorite, but there are far worse problems in it than the droid torturing. I do often think about it, though, when it's up. It does make me chuckle a bit, moreso for 3PO's reaction than anything else, but it does cause me to wonder for a few moments what sense it makes. Maybe if it was only lacking that garbage can having his feet burned it would be okay. The droid being torn apart on the rack (the one 3PO's distracted by) isn't as goofy, and I also love the fact that 3PO's desperate reach to R2 as he's being carried away matches the dispatched droid behind him. Maybe it's just that one foot-tortured droid that pushes the scene into the realm of WTF.
