I'm not one for crying but :
Less than Zero
The deer hunter
The black hole (I was like 8 and when the old robot B.O.B died i was inconsoleable hehe)
Braveheart and Patriot just made me cry cause of how woefully inaccurate and the fact they made the british army into Nazi's in all but uniform. Take Braveheart - the hero was a barbarian who in many documented cases killed off entire villages's adult population then herded the orphaned children into the church then burned the church to the ground... what a hero lol.
