Hate it. So the message of Andor is it's ok to commit murder as long as it for the benefit of the cause. So the ends justify the means. Great Messaging Disney. That is not what Star Wars is about.
If you liked 'Rogue One', you'll likely enjoy this prequel (set five years before Rogue One).
Some familiar people, places and creatures, but also some unfamiliar ones.
I personally love the flashbacks to Cassian's childhood. It helps to flesh out his character and explain how he became the person that he did.
It's gritty and realistic with great cinematography.
Some might say it's slow, but do yourself a favour and watch the first three episodes in close succession... as they really do fit together as a movie length introduction to the series.
