This episode is a dud. Lawrence could have been MUCH funnier in that "rude waitress" diner sketch. I don't know why she chose to dead-pan it. Would have been funnier if she was more eccentric.
In every sketch she's been in, she's had the same low-level, even-toned energy. Wish she would have chosen to go outside the box.
Seems like the writers tried to blend her in as best they could, too. This was especially apparent in the "cool kids" sketch where she played the laid-back emo stereotype.
I've seen Lawrence in a lot of press interviews recently, and I can tell that this "energy" that I speak of is just who she is. You can see it in her film work, too. I do think she is an exceptional actress, but it doesn't seem that eccentric, high-energy characters are her thing. SNL was maybe a bad choice for her (though I understand why she did it).
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
