I was watching the latest episode of New Girl the other night -- yeah, what of it? -- and I laughed at a few bits. Don't ask me to recall them; like most sitcoms now, the humourous stuff falls almost instantaneously out of my head. When you give even one extra moment of thought to New Girl, it falls apart. It is a deeply dumb show, filled with deeply dumb characters, doing deeply dumb things. But it is funny at times, which makes it worth watching. Sort of.
This is a common trend with good sitcoms.
