I know the last user thought the episodes were just average, but you cannot judge very early 60's TV by today's standard and technology. The show was very cool, and so were Napoleon and Illya. Heck, that is why there is still a huge following forty years later.
Yes, the shows look as if they were filmed on back lot. They were. The pace and budget did not allow for on location scenes. Look at old Star Trek and you will see the same limitations.
Many shows were intended to be funny or at least tongue in cheek. The episode with Joan Collins is a riot. The agents are trying to get a low class woman to pass off as a lady. This episode, The Galatea Affair, is a take on My Fair Lady and introduces Noel Harrison as Mark Slate. OF course you will remember that his father had the task of transforming Liza Doolitle in MFL.
Try the very early pairing of Shatner and Nimoy in Project Strigas or The Ultimate Computer Affair, another great MFU episode. There were over 100 of them in this popular 60's show.
