I think the film "Goonies" is partly unrealistic. Why for example does the ship comes out of the cave suddenly? Some parts are foreseeable. There were some frightening moments which are supported by the music. So without the music it wouldn't be so frightening. This frightening and sometimes exciting moments make this film an adventure film.
 There were some funny moments, which is also good.
I would say, it's good to have seen this film, but I wouldn't see him again.
