Back in 1977, no one knew if George Lucas' space opera Star Wars would be a hit, or be remembered years later. Especially Lucas. Then he had to come up with a continuing story, which ended up being full of plot holes. Rabid Star Wars fans know this, and cannot stop talking about them. After seven movies in the saga, we get Rogue One, which was shoehorned into the time slot just before the first film (now called A New Hope) and patches up a big plot hole. There are plenty more where that one came from.
3. Leia’s Mother
Leia stated in Episode VI that her mother was “beautiful,” “kind,” and “sad,” which suggests personal knowledge. From Episode III, we know that this is impossible because Padme died not long after childbirth of a broken heart, which sounds over-dramatic but is indeed a real thing that can happen.
4. Skywalker Family Connection
There seems to be some sort of special connection between the Skywalkers, as shown by how the twins were able to sense one another as well as how Darth Vader was able to communicate with Luke via telepathy. However, this makes it strange that Darth Vader never noticed that he was torturing his own daughter in Episode IV, which must’ve made for a crushing surprise when he found out.
You'd think that if Lucas really wanted to tinker with his finished films, he would have changed the plot holes instead of adding CGI to the "special editions."

R2 is from Naboo, along with Palpatine and Jar-jar, both strong Force users.
