How about you just read it and find out for yourself? Maybe you'll find out that the Disney stuff isn't all that bad. I know, I know, what a crazy concept, right?

I happen to be someone that enjoys both the new AND the old, and can do so simultaneously (and can also see where the EU/Legends stuff isn't always good). My favourite Star Wars character of all time, Kyle Katarn, isn't Disney Canon, but so what?

Seriously, just give it a shot. If you must know, the books came out in the last few years, long after the Disney purchase, so assume that they're "Disney Canon".
