New Year's resolution is to catch up on classic films I've never seen (the list is embarrassing. Jurassic Park, Ghostbusters, Star Wars IV-VI, Alien, etc etc etc). Got a list of 100 ready and waiting, ticked off 3 so far.
Pulp Fiction was great, but I'm not sure Gremlins or The Goonies are films I'm ever going to feel any desire to watch again. I can see why they're classics but not big on either of them tbh.
Working through a list myself, saves me wasting time deliberating over which film to watch.
I've missed similar big films, I've watched all the ones you've mentioned (watched Ghostbusters recently - pretty crap if you ask me) but missed some classics like The Godfather.
Similar opinion on The Goonies got pelters in work for it.
