My dislike and ranking of TFA is based on the overall plot and my general dislike of J.J. Abrams and his work (such as the atrocity that is Star Trek Into Darkness). He is a master of writing characters, but he sucks at telling a coherent and complete story. I am so glad someone more competant is doing VIII and IX. Someone who knows story and characters and dialog.
Funny you bring that up, because my two daughters had to ask a million questions watching the PT. They had no such trouble with TFA.
