While Jedi may have some of the best moments in Star Wars, it's always felt to me like a disgraceful let down.
ANH started the thing off with a real blast but ESB took everything to a higher level.
Better photography, better acting, better direction, more interesting story and character development, better score, and better special effects.
Jedi was a step backwards in almost every field.
I am reminded of the line attributed to Dolly Parton that "It costs a lot of money to look this cheap". It took a lot of effort too but it just looks, sounds and feels like something cheap and tacky (like when the same Cylon Raider would blow up sometimes three times in the same episode of old Galactica). I wanted to ignore the wobbly ugly mess because it was Star Wars (I'm a Doctor Who and Blake's 7 fan so I'm used to putting certain things to one side in my brain but those series usually had something interesting going on to cover the lack of money and glitter...this was a dodgy tale built of little more than dodgy glitter which must of cost a fortune but looked cheap).
Where the Star Wars galaxy seemed huge and complex in ANH and maybe more so in ESB. ROTJ reduced it down to a few planets and the Empire down to one fleet and a few old guys in funny hats.
Nothing has shaken my initial reaction of it being the contractual obligation film and if it wasn't for the charm of even the half hearted performances of the original cast and Ian McDiamid doing a lovely old git it would be just as awful as any of the PT films.
It marks the place where George got rid of anyone who would question his decisions and where Star Wars hit the skids.
