Number one is Empire cause it still rocks from start to finish.
Number two is Attack of the Clones ( Yoda, Clones, Darker plot)
Number Three is ANH the one that started it all ( Good starting Point)
Number four ROTJ cause I thought there was too many Ewok scenes.
Number five TPM way too much Jar Jar but I still enjoyed the film from a kids point of view.
All and all this is how I think the majority of this thread is going to go with ANH fighting with ROTJ for third spot. I may be wrong but that's my opinion.
