I personally hold this one to be the best of the entire series. I remember the music queues, as has been mentioned earlier in the thread, and racking my brain trying to place them for their familiarity.
I also thought there was a great Protagonist/Antagonist Chemistry between the Baron and Indy. I remember watching the rest of the series hoping that their paths would cross again at a later time. In my opinion he was the Belloq of the chronicles.
