Abrams knows all of your criticisms of The Force Awakens. He has, on multiple occasions, acknowledged where he messed up. I have full confidence that he is going to build on The Last Jedi and knock Episode IX out of the park.
Also, I thought The Force Awakens was phenomenally shot and directed. Not all that original, sure, but just a very, very well-made movie. If he can bring that, and get some originally in the script, Episode IX will be amazing.
