+1 on laziness using movie themes. I recall a lot of themed titles in the early 80's like Charlie's angles, a couple of bucks, kiss, Ted nugent etc but yes there were lots of originals.
What I don't understand or should I say I haven't seen any numbers on breakdowns of current pinball sales ie. home to operator sales why movie themes are purely the go. I think this is why I haven't jumped at the opportunity for a new pinball. I enjoy my originals a lot more than my themed ones except for TZ. So if the man market is home users the manufacturers should heavily look at a original concept that will allow for lots of new ideas. I like scifi or horror myself.
