Virtually none... the queue alone is over the top for people that love the franchise. All young boys and a few girls will love it and all the prop cars on display. The actual attraction isn't a straight line like Hollywood and this one will contain at least two additional scenes, one of them very large. It is unclear what might happen in either.
I really REALLY hope that the last one isn't a "bye friends, good work" musion from the cast. I find that soooo tiresome.
