I like all Star Wars movies differently.
ANH - Classic stand alone movie, great 70s film aesthetics of less is more and lots of visually driven shots.
ESB - Great character piece, very funny in parts and very tragic in others. Very 80s in tone and feel.
ROTJ - Popcorn movie through and through, with some truly epic finale moments.
TPM - Good mix of the old and the new, I loved the art direction. Lots of cool reveals, like how the Jedi Order functions and what the Sith are. Great final battle, best saber fight in the saga. Oh and the podrace is always a great visual/audio showcase.
AOTC - Like ESB, always loved the mood and atmosphere of this movie. Also, there was a fair bit of much needed humor. Dooku and Jango were standouts for me.
ROTS - A true space opera. I love the grand sweeping feel of the movie, and there are so many OT bridges. I just love this move.
TFA - Solid tribute to the OT and a great beginning of a new trilogy. Honestly, loved the new characters more than the returning ones.
