I liked it enough. Some of it was a bit "meh" to me, like the pretty cliched parts of the set up. The disgraced agent being transferred, who also happens to be the smartest one and only one that figured out what was really going on. And the boss that won't listen and it blows up (literally) in his face.
I'm also a tad bit "meh" about the fact that Heller is President. He seems a bit old to have been a popular choice for President considering William Devane turns 75 this year, and it's another 24 convenience on who the President is (Wayne Palmer anyone)?
But I liked Jack and Chloe's reunion, because it didn't get nostalgic or mushy, it was right back to awkward and serious.
