Yeah, really not a great must see film. I think if you were to ask yourself, "if this wasn't a Star Wars film, would I pay money to see it?", the answer would be no but you might stream it if you are bored and looking to watch anything sci-fi related.
I also think that the writing in particular was something I'd expect from a made for TV film. It feels like it was written for television as part of some expanded universe, made for fan service but not good enough for a cinema release. I wonder with all their current issues -- Kathleen Kennedy rumored to already having been fired -- whether this may be a better strategy for them regarding Star Wars anthology films. Make them streaming only releases, like you find on NetFlix but instead for Disney's own streaming service. Which I've heard about. And for cinema releases, trilogy films that come out every other year. Oh, and non-EA Star Wars games... books... comics... if they can fix their problem before Star Wars is dead to the majority of fans.
And yes, I have seen the film and no I didn't watch it at the cinema -- and I'll leave it at that.
