You could gp look at Legends, but gone are the background detail and depth from the new stuff because they want to package it for marketing, not actual literary depth and deeper meaning. They have turned it into a cotton candy version.
Literary depth? That's a joke. I stopped reading Star Wars and Star Trek novels because of the lack of consistent literary depth and because, in my opinion, too many bad authors kept getting commissions to write stories. I found "Courtship of Princess Leia" to be horrible right from the start with Han and Lando fighting over ownership of the Falcon after that ship had flown and the two characters had grown past this particular childishness by the end of ROTJ. Kevin J. Anderson I find to be an awful author with unoriginal ideas.
When I can go down to my library, or grab my kindle, or whatever and read it whenever the fuck I like. Seriously? Lost? Lost implies that I cannot get it any more. That I cannot read it, or enjoy it. Yet that is distinctly not the case. Not at all.
I see this raised often during discussions continuity. This objection is made by people who favor the changes to continuity, the reboots, the retcons, and wholesale changes that other people strongly dislike. This objection seems to miss the point of all the angst. Yes, we know we can always go back and reread these now obsolete stories, but nothing new from this incarnation will be produced. No new stories about Jacen, Jaina, or Anakin Solo. No stories will reference Thrawn and his encounter with Mara Jade, etc... It's like when a person's favorite band breaks up - sure, you can listen to the older albums and enjoy the separate works of the former band members, but this particular musical journey is over.
As time goes on fans will forget these obsolete works. I much prefer the Brian Daley trilogy of Han Solo stories over AC Crispin's trilogy. I was not a fan when Crispin's books became the "official" story of Han Solo's life. Doesn't matter now because those stories are now obsolete as well. Yes, we can go back and read them again, but a third telling of Solo's life is probably already out there (for the record, I loved "Solo" but disliked the direction they took the character by the start of TFA).
Some fans are simply tired of unnecessary reboots or changes, especially if they feel the change is stupid and the old ways are cool. I much preferred the history of R2 and 3PO as depicted in the "Droids" cartoon. On the other hand, I don't believe any of us gave any of the Ewok TV stories any serious consideration to their place in continuity.
Since I stopped reading the EU in the early 00s, I'm not as emotionally attached to the now obsolete novels and I enjoy how they are pulling in old references even from the dumb stuff like Blurgs or the MiniRigs or the Troop Transport.
