I am still completely aghast at that timeline in the new canon. The EU seemed like a sensible progression of Imperial collapse... And we know how ridiculous it was at times.
They've done some interesting things during the Clone Wars/Rise of Empire era from what I've seen/read/heard but while there have been good stories, there hasn't been anything suitably epic or good like what the EU had. The best of the Disney canon material is merely
Truce of Bakura level quality as opposed to
Thrawn Trilogy level. The Thrawn Trilogy, Knights of the Old Republic games, the Dark Forces games, every other New Jedi Order book, and several of the comics (including some excellent storylines in
Star Wars: Empire) all had great stories that in the past few years Disney canon hasn't really managed to match, especially in the post-Endor era.
I haven't read the Aftermath trilogy but one of my friends did and was telling me about it. Like the first novel was super fast paced that they actually slowed shit down for the second one... so it actually read better. But there was a lot of 'explaining' exposition like... Oh we lost Kuat already... and eleven of our SSD's so only one is left and a quarter of our Fleet disappeared, and half was destroyed by the Rebel Alliance somehow... which is already the New Republic. Apparently it was decent enough read.... but still lame. So the overall story quality is zero... but the writing multiplied that zero by like... twenty times by the end. But that's still zero. Just so truncated. I wonder if it's limited by trying to explore everything while fifty movies/tv series are being planned in the same era or something. Either way it doesn't make for a good Disney version of the EU.
