The only problem I have with the Book of Boba Fett is that the last two episodes have basically not included him at all. A better title might be "The Book of it's actually Mandalorian S3 and also we're setting up at least one or two other spin-off series".
Mind, yesterday's episode was fantastic. Without wishing to spoil, it was Fan Service done right.
It's the fact that these characters are appearing in service of the story, rather than the other way round, that's making it work. But I absolutely melted when I saw the first on-screen conversation between **CENSORED** and **ALSO CENSORED**, which I've been waiting for ever since I fell in love with a character who shall remain nameless but is also rather easily guessable.
I've watched all manner of Star Wars stuff and conclude that the best are the original 3 films Episodes 4,5 and 6. Episode's 1,2,3 were ridiculous. Rogue one is probably best of the rest.
