Question

ENTER DARK STRANGER
by William Trowbridge


In Shane, when Jack Palance first appears,
a stray cur takes one look and slinks away
on tiptoes, able, we understand, to recognize
something truly dark. So it seems
when we appear, crunching through the woods.
A robin cocks her head, then hops off,
ready to fly like hell and leave us the worm.
A chipmunk, peering out from his hole
beneath a maple root, crash dives
when he hears our step. The alarm spreads in a skittering
of squirrels, finches, millipedes. Imagine
a snail picking up the hems of his shell
and hauling *** for cover. He's studied carnivores,
seen the menu, noticed the escargots.

But forget Palance, who would have murdered Alabama
just for fun. Think of Karloff's monster,
full of lonely love but too hideous
to bear; or Kong, bereft with Fay Wray
shrieking in his hand: the flies circle our heads
like angry biplanes, and the ants hoist pitchforks
to march on our ankles as we watch the burgher's daughter
bob downstream in a ring of daisies.

Answer 1

The poem is just describing a nature setting and shows how chaotic and meaningless life and existence is, in essense what is the point of EVERYTHING?

Answer 2

The poem is explaining something very scary. All the animals are running away. Even the snail is "picking up...his shell and hauling @ss for cover". Everything is scared of Jack Palance.

But the author also explains Jack as a tragic character like King Kong. King Kong is scary but at the same time we feel bad for the monster. Frankenstein (Karloff's monster) is ugly but has love in his heart.
