Light Sabres! :roll:
Star Wars swords indeed :lol:
The very first Star Wars was ground breaking in so many ways, it deserves a place. It's also a good film actually... Not as great as most Star Wars fans big it up, but it's "good". Empire Strikes Back is a much better film in terms of story and direction, but... You have to be engaged with the characters and plot from the first film for it to effective.
Essentially, the only film worth watching to see if you like the films is the original; that's Episode IV: A New Hope. The rest aren't really worth your time if you've not seen that/don't like it.
The Goonies is excellent, but not for any good reasons. It's Indiana Jones lite and a little bit too twee. Spielberg just makes something out of the dog's dinner it is. Some brilliant adventuring and the fantastic sloth really make up for most of the lacklustre meandering of the film. It's not a good film, but it's fantastically charming and a perfect example of a great kid's adventure movie... Except the dull half an hour or so start.
