This one felt a little dull to me. The opening was great with Krusty's Absolute Vodka brand, but the rest of the episode just felt a little boring. I did like Marge trying to talk to Marlowe and ending up in different rooms.
The B-plot didn't do much for me either. Bart reading Little Women to the bullies led to a few chuckles, but it was nothing great. And doesn't Bart already know how to read?
Au contraire, sir. I thought this was really good. A notch below last week's The Book Job and the food blogger episode the week prior, but I feel like the last three episodes have deliberately catered to stuff I find funny/interesting. This week's Mad Men spoofing was great, with John Slattery basically playing Roger Sterling. And they even parodied the lawn mower moment from Mad Men, arguably the craziest moment in that show's history. Plus Homer turning into Don Draper and Marge's time jumps with Marlowe into his bed and in his shower were awesome. This has been an unusually strong Simpsons season thus far.
Now this is just me, but I personally take the plummet of O'Brien's not as evidence that he's a flop by TBS' standards, but as evidence to reinforce my opinion that he's just not very funny or entertaining.
