Goonies was Raiders of the Lost Ark for kids. It had action, adventure, and plenty of hilarious moments. The selling point is clearly getting to see a group of outcast kids being the unlikely heroes as they find a treasure map and make it through the diabolical and mischievous traps left behind by what feels to me like the movie's prime antagonistic force: One Eyed Willie. It is a movie that is certainly not going to have the same magic if you watch it now for the first time. You might enjoy it alright, but you certainly won't be able to make any kind of connection with it.
My favorite scene is where Chunk has been captured and is being interrogated by the villains into telling them "everything", in which he immediately starts to recant every mischievous prank he has ever pulled including the infamous story of going up to the balcony of a movie theater and pretending to vomit. The genuinely pleased look on the older Fratelli brother when he puts an arm around chunk and says "You know, ma, I'm starting to like this kid" is priceless.
