The endless capacity of Kevin's stupidity
SPOILERS!
I love the actor, but boy, the way Kevin's character is written . . . It nearly borders on poor writing, because it's so hard to believe that any one character could be such a ceaseless font of stupidity. From keeping the coke to selling it; giving it back to Lowry, thinking that they'd all be square after; to insisting giving up the whole story to Marco; then killing him. It's just not realistic that someone can be so consistently stupid and still be alive.
Same with Meg—it really seemed out of character to have her suddenly turn on John.
John is right about the both of them. To hell with 'em.
You have to blame the father, Robert, here, for how F'ed up they all are—but I think Beau Bridges's character will be the ultimate villain (he will be found to have tainted Robert somehow, which leads to the whole mess, I think).
But really, the whole family needs a Jaws attack.
