Didn't enjoy this one at all. It strongly relies on remembering lots of the minutiae of the original trilogy, which I personally haven't seen for over ten years, so I just felt no connection to many of the characters.
The action sequences are a confused mess, not living up in any way to the style or originality of the first film, and everything in them has been done before now a hundred times in other films.
Simply breaks no new ground whatsoever, and adds nothing further to the original story, other than to totally devalue the ending of the trilogy.
