How come that the imps could tell there were no lifesigns aboard the escape pod R2D2 and 3CPO fled in but they were unable to detect three adult human and a wookie on the Falcon. How come Anakin could find his mother in a Tusken camp in the middle of the nowehere in the 2nd episode, and he, as Vader, was also able to communicate with Luke in the fifth episode, but he wasn't able to pinpoint Kenobi in ANH when stood next to the Falcon? How come that Anakin was a master of swordplay in the third episode and, as Vader, he was quite fast in ROTJ but he moved like an overloaded mule in ANH? And so on. Btw we didn't see enough Darth Vader evildoings in the six parts. And for that, I will hold grudge forever...
