Obviosuly my favourite is Star Wars, but here are all the series I like.
Star Wars - (tie) A New Hope, Empire Strikes Back
Die Hard - Die Hard
James Bond - The World is Not Enough (though I haven't seen any of the old ones)
Batman Movies - Mask of the Phamtasm (unedited ROTJ is close)
Believe it or not, it's been too long since I've seen Indiana Jones, and I can't remember any of the 3. I kinda remember Temple of Doom, but until someone told me, I didn't even know Connery was in Last Crusade!
