Whatever. I had no problem believing the Ewoks could take out the ground troops. They'd proven time and time again they sucked at everything. Look at all the shit they did: the logs were ingenious. And you clown have you forgotten how the rebels took out the walkers on Hoth?? They used friggin tow cables and tripped them. The Ewoks did more with logs then just trip the AT-STs. They sent them flying at the cabins, remember? Friggin ingenious. And tangling up the Speeder Bikes with rope... it showed that primitive creatures (by your definition) could take out the "advanced" forces. I always loved that lesson...

The Gungans on the other hand showed that creatures could have advanced technology and still suck.
