Everyone is entitled to their opinions and I respect yours, I would offer a different view point on those four items though:
Holdo is a leader/vice admiral whatever… why would she tell every captain (ie MINOR leader) her plan? We have established that the first order has spies already, also like any military structure, most plans are on a ‘need to know’ basis and why would finn need to know? I don’t think it was just a plot device, I think it was about trying to teach Finn how to be a LEADER, not just ‘get in an x-wing and blow things up’ flyboy. This character ark is further confirmed when Holdo says to Leia as the transports are loading “I like him” etc. Also note that Finn and a handful are the only ones running around trying to do a different plan… everyone else seems happy to follow Holdo… perhaps some of them did know the plan in advance?!!
Agreed the extended space chase was bad… it was a poorly executed plot structure to allow for side adventures… however Star Wars has been using these forever. Stormtroopers that can’t shoot… a ‘back door’ to the power station… hiding in a worm whilst the entire fleet floats past you… hiding as space junk and not appearing on any radar… the ‘bad guys’ never being able to deal with a ‘singe fighter’… I mean seriously the list goes on. It seems a tad foolish to pick one out in this movie to go on a list as to why Star Wars is dead to you… I mean how many times can the Millenium Falcon hyperdrive not work thus meaning they can’t flee…?
Finn was trained as a trooper… perhaps it included basic flight training… and they weren’t really flying… more like gliding/ski-ing… maybe the same as hiring a jetski at the beach during your chrissy holidays!!! Also, we have seen this plot device used time and again… Luke jumps in an x-wing and literally takes down the death star and yet you still watch Star Wars… oh but he flew a crop duster so all good yeah?! Perhaps Rose gave him flying lessons on the way to the casino?!
Humour was ALWAYS a part of Star Wars OT… How about in the middle of the most intense prison break in galaxy history when Han made a ‘prank’ call to the control room?! Or the entire scene of Luke meeting the mystical and masterful yoda… when the force is coming into view… and we are popping wise cracks about his size and he is acting like an foolish cartoonish old man… yes yes?!! I agree we lost that sense of humour a touch in the prequels and they were the lessor for it… We gained a little back in the FA (don’t hold my hand anyone!!!) and TLJ really turns it up. FWIW the jokes may not be your cup of tea but my 12 year old REALLY loved it… and was one of the biggest highlights of the movie for her… and yep they are targeting kids… no crime in that. The OT was targeted at kids too and that worked out just fine.
I don’t think there was meant to be a romance… I think there was meant to be a hero worship type infatuation… and possibly love interest down the track. Finn is a ‘resistance hero’ who’s story has been told around the galaxy… one of the MAIN reasons why Rose and her sister joined etc etc… it would be like meeting a rock star… she goes a little giddy. There wasn’t much passion there because Finn is clearly interested in Rey… So I think it was meant to be awkward and one sided. Again focus on the plot device which was the notion that they need to stop fighting to kill things but instead start fighting to save things… which also ties in with deepening our understanding of ‘force balance’ too…
I’m sorry that you, and so many other people, did not enjoy the film. I really am. I hope that over time those fans will be able to rewatch it, with fresh eyes, and it will gain more respect. TBF most people hated TPM at the time… no one thought SW would survive Jar Jar… but it did and here we are.
