The Empire Strikes Back
The Force Awakens (in terms of characters, dialogue, acting, action, a layered/compelling villain, special effects, comedy and the way it sets up Episodes XIII and IX TFA is vastly superior and in general is a more ENJOYABLE film to watch than STAR WARS)
STAR WARS (has a better plot than TFA but falls short in just about every other way)
Return of The Jedi (great resolution to the OT but Ewoks kill the pacing and Death Star 2.0 was unnecessary)
Revenge of The Sith
The Phantom Menace
Attack of The Clones
