Unfortunately disappointing

Rating: 6/10 (17 December 2017)

When I was five years old, my friends and me came by a garden with a big rabbit stall. What's that to do with Star Wars? Bear with me... I saw the rabbits in their little cages and was sure that they were about to be killed and eaten. So we decided to free them. We climbed the fence and opened the cage doors, then quickly flew the scene of our crime. We were caught later and informed that these animals were pets and not food and that our action had put their lifes in jeopardy. If only we had a grown up with us... but what is Poe's excuse (Spoiler warning!)?
He thinks all the rebels will be packed into little transports and killed. And thus plans to free them (by finding a way to escape the First Order). In doing so he ends up killing most of them (95% is my estimate), because his very complicated plan gets leaked to the baddies and they start shooting the transports.
If only someone had told Poe that there was indeed a plan to save everybody, that there was a base on that planet, then he might have seen the error of his ways and not let the rabbits out of the cage... erm... you know what I mean.
But unfortunately Admiral Holdo does not deem him trustworthy and even as he calls er up on her seemingly stupid plan and then commits mutiny, she still does not fill him in.
I know that is just one plot of the whole movie (the main plot nonetheless), but it shows the biggest flaw of the whole movie: it seems not fully thought through. Characters appear out of nowhere and disappear as fast. Snoke, who looks great and is played well by Mr Serkis does not have a backstory that would describe his deformed looks. He seems omnipotent until he isn't.
We are supposed to care for Rose because her sister died. But sadly we don't, because that is the only thing interesting about that character.
Admiral Holdo is sympathetic but otherwise completely bleak. She serves her function but nothing more. (And since she knew she was going to die on that ship, she could have had her kamikaze idea a little earlier and thereby saved a lot of lives - damn, she almost destroyed the whole enemy fleet...)
And what's up with Leia's godlike yedi powers? Downsizing would have been a great idea for this one. She does something we have not seen any yedi do before. Not even in the horrible prequels...
Enough ranting - here are some positive aspects.
The Rei-Ben-Plot works quite well. The connection between them is a great idea. That both of them think they can change the other one is fantastic.
Luke's holding off the troups is ingenious. Unsuspected and fun. Why does he die afterwards? We don't know... Yedis, am I right?
So concluding I would summarize that the movie is entertaining and has a lot of great moments. But it does not feel like a great movie. Too many scenes left me wondering and irritated or worse...indifferent.
