So, I am not a prequel hater. I love the prequels as much as I love the other movies (Revenge of the Sith is tied with Empire as my favorite episode.) I realize that they are flawed (all movies have flaws), but I don't let that get in my way of enjoying the story. To me, Star Wars is Star Wars - I love it all.
It should be noted though that during the prequels, it was pretty well-known that it was George's way or the highway. So when you criticize Lucasfilm as a whole, just realize that during that time period, decisions were ultimately up to George. (I'm not taking shots at Lucas either. The guy created all of this - it's his baby.)
Now, GL is gone, so TFA was the first generation of post-Lucas Star Wars films. And for the most part, everyone loved it. That's why I say have faith in the Lucasfilm story group. When the movies were totally under their control, they delivered. They played it safe by paying homage to the OT, and now with Episode 8, they have a real chance to shine.
Additionally, all of the extra material that Lucasfilm has created since the prequel era (The Clone Wars, Rebels) in my opinion has been spectacular. For the limitations that the story group has, since they are kids shows, they've done the absolute best job they could do with those shows. And Rebels season 3 looks like it's going to be no different. Dave Filoni is a genius.
Anyways, that's why I'm excited for the rest of the sequel trilogy and why I have faith in Lucasfilm. I loved the prequels - it's no secret that they were flawed but they're in the past now. The Clone Wars, Rebels, and now TFA have ushered in a new era of Star Wars story telling that has, so far, delivered.
