The problem is that dialog between Owen and Beru suggests they were well acquainted with Anakin, but AotC reveals that they only met once and barely had any interaction at all, making their concerns about Luke being like his father odd.
Like I said, I think the PT paints a different picture than what you might think, but not one that actually contradicts anything.
Owen is concerned in that scene, while Beru doesn’t seem as concerned or concerned at all by the comparison. Which could fit with what they both took away from what they could glean transpired to allow Anakin to get his mother back. They also briefly met his wife, and also spent years with his mother who we know talked about him, Owen says so. They would know that he was a good but intense man who may or may not have fought his way through a horde of Tuskens to rescue his mother.
They also know that either Luke’s father is dead, or that he is Vader (highly unlikely), so either way, being a Jedi ended poorly for him.Furthermore Obi-Wan tells Luke Owen and Anakin strongly disagreed on matters. How would Owen know anything about Anakin’s convictions if he barely said “hello” to him?
“Didn’t hold with your father’s ideals thought he should have stayed here and not gotten involved” and “wouldn’t allow the lightsaber to be given idealistic crusade etc” are the only lines I remember given, and they are both easy. Owen is a practical man, a family legacy farmer. Anakin going off to be a Jedi ultimately left his mother alone, and got him (and her in a way) killed. He doesn’t say “convictions” he says “ideals” meaning the Jedi way, the fool idealistic crusade way. Ultimately the Jedi all got wiped out for their crusade, so why would Owen let Luke down that path?
We don’t need to see Obi Wan and Owen discussing the above quotes in the PT, it is fine that we hear them in Episode 4. It’s all one story.
