I recently rewatched The Goonies because like Rik it was one of my childhood favourites, but to be honest it really bored me, those others that Rik mentioned though do stand the test of time much better.
I watched Gremlins 2 last night finally - haha I never realised it was so gory at the end it's pretty gruesome, obviously as a 13yr old it didn't phase me at the cinema. I got a kick out of the soundtrack though, Slayer and Faith No More when Gremlins were up to no good
and Christopher Lee is brilliant fun. It was weird seeing 'The Doctor' from Star Trek Voyager though aha!
