All the dialogue and set-up in the latter two Jurassic Park movies. I know they're just there so the dinosaurs can wreck their shit, but I genuinely do like it. Besides, I think the trailer scene in JP2 was just as good as the car scene from JP1.
EDIT
I've never really had a problem with filler. To butcher a quote; "Drama is life with the boring parts edited out." If anything, filler tends to have a more humanizing and world-building characteristic to it because it displays characters in situations apart from the main conflict. What do they do in their spare time? Do they always obsess over the important stuff or do they put it out of their minds? How do they react in mundane situations? etc. etc.
