Yeah, see that's where I differ. I've never read a single bit of EU. The films are and will forever be my canon. But with the Original Trilogy, I was always a Obi-Wan, Vader, and Yoda fan. Obi-Wan's speech to Luke in his hutt filled enough in my head for me to want to know how it all went down back in the day. I liked Luke, Han, and Leia, but they just didn't have the presence that Vader, Obi-Wan, and Yoda had.
I think Anakin's a far more interesting character, whether likeable or not. His story is just more complex than Luke's. But, that's fine. Their stories and circumstances should be different because they were raised different.
