The case for Rey Kenobi

Your argument betrays itself almost immediately in this post. Previously you stated that these movies need to stand on their own, now you mention how they are tied to all the previous films and other forms of canon media. Here's the thing about that though. Mentioning that ANH was the first movie and TFA is the seventh doesn't matter from the perspective of a first time moviegoer. Both films still imply a ton of history that isn't shown to us in the film(because it doesn't need to be shown). A new fan who isn't familiar with Star Wars is going to have questions after watching either one of the films, but they won't be questions that affect their experience or the story in any major way.

As for Obi-Wan(or any other major character) being related to Rey, that won't trip new fans up in any way, after all, if they are brand new fans, Obi-Wan will be as new to them as any genuinely new character. Also, as @Grand Admiral Kraum pointed out in his last post, TFA is already heavily tied to the prior movies anyhow.

As for arguments as to whether such a thing would be appropriate for Obi-Wan's character, those are perfectly valid arguments to make and discuss. I have no problem with reasoning based on stuff like that, it's the argument about this new trilogy standing alone and Obi-Wan's presence as Rey's relative being a problem based on that which I find silly.

 

How true. While I enjoyed Maul's character since he was brought back, I can't stand the spider legs part of it. It does prove that anything is possible. It also shows there are bad ways of doing it. If they make Rey a Kenobi (or Luke's daughter or a Solo for that matter), they need to be careful how they do it. While the Maul spider leg fiasco was done poorly, they rebounded nicely with the character. The Maul situation was also before the story group. I'm confident that whichever way Rey's parentage turns out, the Story Group will make sure it is a good cohesive backstory and the days of things like spider legs are in the past.
