What are some good movies?

I've just recently watched 'Brave Heart', 'The King's Speech' and
'Good Will Hunting' because my parents said I'd love them. and I DID!

Now I'm in a real movie mood and was hoping for some suggestions?
Hopefully ones as good as those above! Keeping in mine that I'm 14
(nearly 15) and while I am mature and don't mind most things, could
you try and keep that in mind with your suggestions? :)

Thank you! :D
