I think Leo's gotten more tolerable as he's aged. I'm still not a huge fan but I liked him in Gangs of New York.
I've never seen this movie but have this anyway:

I'm not a huge fan of his but I do like some of his work. Gangs of New York is definitely one of my fav's.
I even liked Catch Me if You Can. He was quite good and pretty charming in that one. I own the DVD.
I still think his most memorable performance was in Gilbert Grape though. Blasph you need to see it immediately!!
I love it when he kills the grasshopper in the mail box. He decapitates it then runs crying to Gilbert saying "Killeded it Gilbert, I killeded it!!" I am purposely spelling killed with two ed's too because Arnie pronounces it (Killed did). aha
Oh and that gif you posted is where he is in the tree saying -- Ooooooh Dad's down there! Dad's Dead! Dad's dead!
Which of course, he hides in the tree many times throughout the movie. He even climbs the town water tower.
Match in the gas tank BOOM BOOM!
EDIT::
Oh now wait... Are you calling ME a retard Blasph?
