Actually, that analogy should work to people who like it. At least in my case, I like Scott Pilgrim, and everyone I know who has seen it likes it. However, most people who haven't seen it will not watch it, not being able to grasp the fact that it is actually a good movie. Ejector airtime seems to work the same way to many Californians, as they do not know how awesome it is, and, therefore, assume it is not that great and giant loops are better.
In fact, if it weren't for Scott Pilgrim's high Rotten Tomatores score (that it deserves), I may have never watched the movie. However, this same website gave Adventureland an 89% (of which I think it does not deserve)
In fact, to go back on topic, I really hate movies like FD3 and Adventureland, that depict amusment parks as being unsafe. It really dumbs down people's views on the industry, causing the usual GP 'roller coasters aren't safe!'
I apologize I misunderstood what you meant. I don't really rely on reviews. They look for specific things and pick it apart. A movie is to escape reality. So is a theme park. You go there to have fun and not think of everything for a couple days.
