If you want some scifi in your spyfi, check out Counterpart (on prime but I think you need one of those bolt-on subscriptions so I condone stealing it).
Cold war spy thriller, but what if the other side was a parallel universe instead? Stars JK Simmons on top form as the mild-mannered this-world bureaucrat who gets mixed up in his that-world spy counterpart's business. All the actors play two versions of themselves and have great fun doing so. Two 10ep seasons and wraps up all the loose threads but then creates a brand new one just in case they got picked up for a third. They didn't, so just ignore it.
