I liked the new thinker tailor more. It had a old school feel to it where they don't spoon-fed you the story and you have to really pay attention to not miss important clues.
They don't make many movies like that any more.
If you haven't watched the BBC Tinker Tailor, you're missing out on the canonical Smiley, though.
Burton's Leamas in Spy Who Came In From The Cold is probably the GOAT though.
Thing is, that was 10 hours per season. It was a futile task to try and cram that into a film; more so than most series/books because it has a fucking confusing plot. It'd have lent itself better to 2/3 parts - and then onto Smiley's people, which IMHO is even better!
BBC version was okay, but felt really low budget. The sound for example was pretty bad for a BBC production.
It was a good movie and true in all other respects to the book.
Having read the book, the big thing I feel they didn’t really convey as strongly was the sophistication of Karla’s “clever knot”. I think that was glossed over a bit.
Granted it’s a pretty subtle thing to depict, even in a film as subtle as this.

It also exposes an unpleasant historical reality: there were quite a few people within both the Soviet and American military-industrial and intelligence complexes who were unhappy to see the Fall of the Berlin Wall and the end of the Cold War, as it meant they lost their raison d'etre... Looks like they're back in business, though.
Le Carre's bleak masterpiece "A Perfect Spy" was essentially about his father's impact on his life.
Oof!
