I think what happens is, people are trying to figure out what's wrong with the show and how to make it better -- things like, it needs fewer random cutaways, fewer long jokes, a more coherent plot, more heart -- but adding those things still doesn't necessarily make for a good episode. Because it still has to have good gags, and it's hard to go into much detail about that other than... they have to be funny. In theory, the improvements we're asking for should result in a better overall episode, but nothing can really guarantee that it'll be funny. That's sort of a magic element, the part of the show that's unique and can't be constructed via committee.
Of course, last week's episode quite clearly failed the "no overly long jokes" criterion. The first conversation about movies entered dangerous territory, but the second one was exactly like the first except about three times as long. That was pretty agonizing. And I have to point out that nobody I've talked to, on the internet or in real life, liked the episode.
Now, let's look at this week's episode. It had a lot of what was good about last week's, but it also had the gags to back it up. It had a coherent, focused plot. It had some element of heart to it (in typical FG fashion it was ravaged at the end of the episode, but I did honestly feel bad for Joe early on, and that was enough). It was fairly low on cutaways and long jokes. And, finally, it had something new: highly self-referential jokes. They were unexpected, and a show like this definitely has to keep us guessing. The show has settled into a rut where it's becoming more predictable and also giving off a sort of arrogance, like they can do whatever they want and it'll be funny. Making fun of itself might be the way to go -- until that becomes stale.
