"This case appears to bear all the hallmarks of what I like to describe as regrettable misadventure."
Hmm. This isn't bad telly. It's perfectrly fine. But so far that's all it is. Perfectly decent but no more than that.
I suppose Cassian Andor was always going to be a harder sell than Boba Fett, Obi-Wan Kenobi or even the Mandalorian- a new character but a familiar look. These shows harked back to classic Star Wars; Andor appeared only once in Rogue One. Like many others, I've seen the original trilogy many times over the decades, but Rogue One only once. So Andor is a perfectly decent character, but he doesn't have the resonance.
Also, while this is clearly set in the lived-in future of Star Wars, with the tech and general look being unmistakeable... but there are far fewer Easter eggs than previous series on Disney Plus, and all the planets are new. No more Tattooine!
The story is engaging enough, and it's good that we aren't spoon fed either what Kassian is doing or what happened with him and his missing sister as children. It's a nice touch that, so far, the Imperial forces are a distant threat, the immediate problem being highly militarised corporate security.
It's all set-up, of course, but this is nothing special so far. But this is but the first episode...
