Multiple really extreme and pitiful suicide attempts = fun for the whole family!
Any thing where Tommy Lee Jones plays a villain / antagonist - Under Siege, The Fugitive (YOU FIND THIS MAN!), Blown Away, etc. Relish these performances.
Lethal Weapon films - MURTAUGH
Batman Begins - the pacing sucks you in. The one liner ridden script helps a lot too - TASTE OF YOUR OWN MEDICINE, *DOCTOR*?
On the same Lethal Weapon note, any Shane Black scripted movie, particular the Last Boy Scout.
Mission Impossible 3 - monotone hoffman.
All the Ocean films draw me in despite the last two being hacked together because of Soderbergh's quirky direction. Always new things to find.
Miller's Crossing - because it is Miller's Crossing.
Sidney Lumet films - Dog Day Afternoon in particular, but all of them I try to stop and watch every time.
