|Everything wrong with Star Wars in one image|
Putting aside the fact it's all about making money anyway, when you see Star Wars, it's always about swinging lightsabers and using the Force in special effects-laden action sequences.
I firmly hold the opinion that George Lucas completely fluked Star Wars' initial success, mostly down to Ralph McQuarrie's defining concept art and ILM's amazing SFX that set a new benchmark for effects in movies.
But what has every iteration of the franchise done since? Relied on without buidling on it. I'm not one of those Star Wars fans who claims that Episodes I-III ruined my childhood, nor that Return of the Jedi did it, either. In fact Jedi was one of the most-watched VHS tapes I had as a child, just behind Transformers: The Movie. What's wrong is that the swishy-slicey light show that was a highlight in the original three films became the centrepiece of the prequel triliogy and countless games, TV shows and fan works ever since.
