The Prequels were definitely a mixed bag for me. What they did right, they did [i]really[/i] right, e.g. The fight choreography, most of the effects, most of Revenge of the Sith, and a lot of the actors did absolutely fantastic (Ewan McGregor, Samuel L. Jackson, Frank Oz)...Then, what they did wrong, they did [i]really[/i] wrong. E.g. Anakin's entire character, definite overuse of CGI, terrible dialogue writing, [i]especially[/i] for the love scenes, Jar Jar Binks, Midichlorians, and how they completely screwed originally badass characters (General Grievous.) The 2003 Clone Wars series was [i]fantastic[/i] and portrayed a lot of the severely mistreated characters in a much better light. The Jedi were badass, the Sith were badass, the Clones were badass; it was just a fantastic series. 

Now, that's not to say the original series didn't have its own faults. The fight scenes, while very emotionally deep and powerful, were nonetheless clunky; especially compared to the choreography used in the prequels. I felt Han and Leia's relationship was a tad bit underdeveloped, but I could roll with it. The Ewoks were absolutely [i]deplorable[/i] and the Stormtroopers were terribly portrayed. Elite force of the Empire, my ass xD

So, if I had to rank all the films from favorite to least favorite:
[list]
[*]The Force Awakens
[*]Return of the Jedi
[*]The Empire Strikes Back
[*]Revenge of the Sith
[*]A New Hope
[*]Attack of the Clones
[*]The Phantom Menace (Aside from Qui-Gon and Darth Maul XD)
