Since it's a USA show they do seem afraid to get too far ahead of the viewer. So this season, which actually has gone pretty far in that regard especially with the premiere, you still have moments where somebody stops to explain the recent plot. Like in a recent episode someone lectured Annie about how her plan wasn't a plan, only without the concise dialogue of Saint Row IV's "that's not a plan that's a goal."
So that kind of thing can be a bit dumb and annoying, but they really want to make sure people get that while Annie has become beaten down by the spy game and more ruthless in response, she's still naive and inexperienced and relies on her training too much, so every few episodes someone will explain it to her or someone else. Or someone will ask her about what loyalty means, just to make sure you're keeping up that they want to play up that THE SPY WORLD IS LOTS OF GREY aspect.
Some of that gives me concern about how they resolve this season, since they've crossed a number of lines and scorched some earth that you shouldn't just be able to deus ex machina back from but it seems they almost have to in order to continue as a USA show.
Also, I can't help but stand up during the intro and mock everything she does. 
Piper Pirabo is probably the worst actor on the show. This season they sorta are writing around the fact that she only portrays like three emotions. And they've finally put her in sensible spy-craft clothes.
The most hilarious/insane thing about the intro is that they created an episode out of it to "explain" it.
I do kinda miss the song though since they've ditched an intro for just a title card to show things are now serious dudes.
but the show wasn't improving in the quality that I was expecting from it based on previews ("the spy nextdoor... that stays in Washington outside of Mission of the weeks!") before the pilot for it aired.
...
If they honestly resolved that in the past few seasons, maybe I'd return to watching it live, but meh...
That premise and that storyline bombed so hard they've discarded both. There's even been some snark directed at it with things like "Did you think your cover would always be working for the Smithsonian and you'd be home for dinner? That doesn't work everywhere in the real world." (paraphrased)
