So, no TV shows, so immediate fail, but Tinker Tailor Soldier Spy is a wonderful film if you haven't seen it before. Bit of a slow burn though. The Man From U.N.C.L.E. though, much less grounded, but more action packed.
Both are absolutely wonderful! Tinker Tailor is of course classic and a very good adaptation of the book.
Regarding The Man From U.N.C.L.E., I went in blind and really enjoyed it. As you say, it's more an action movie than a nitty gritty spy film, but it's a lot of fun!
