^You may be overthinking this a bit. If stormtroopers can barely shoot straight, how can you expect a droid not even built for combat to be any better? Especially when the prequels & TCW made the point that living troops are inherently better than battle droids because droids are morons.
If that were all that were going on, it might make more sense. The ridiculously acrobatic dodging once the blaster bolts are already in flight is one thing that's really bugging me. It's practically in Bugs Bunny territory. That's something on top of effectiveness of living troops versus droids. To be honest, I'm not entirely comfortable with the cartoon comedy aspects of it.
I said it was a question of degree. Fantasy violence is one thing. But when it's taken to the extreme of cartoon violence appropriate more for indestructible toons, it's something else.
Star Wars has always tried to strike a balance on the fine line between the serious and the comedic even when it comes to violence. For the prototype on how to strike that balance, I return to Episode IV. The opening when the
Tantive IV was boarded immediately and dramatically depicted fantasy violence where people, and good guys at that, were getting hurt and killed. Later on in the film, the main characters had some fun running around the
Death Star, but there was always legitimate danger lurking about them, and Obi-Wan didn't even make it off the station. Yes, his spirit lived on, but not his body. And many Rebel pilots died to bring us the destruction of the
Death Star. It just rubs me the wrong way a little when a show aimed at kids portrays fantasy violence that should be dangerous in a way when the main characters don't have to worry about getting hurt. All I'm saying is that I'd prefer a slightly harder edge here to portray the main characters as being at least a little more responsible and to perceive themselves as being in danger instead of having some kind of ball.
