I am wading in dangerous waters here... but I was quite disappointed   
Since watching it I've been reading reviews have found I'm not the only one walking away shaking their head. It certainly seems a very divisive film!
I thought there were some great visuals and a couple of scenes that were terrific - the rebel ship hyper-driving into the first order's ship - the one stand out scene of the entire movie for me - just WOW!  But.... everything else...
I really felt it was waaaaay over the top CGI in places, like bad on the prequels level (I'm not a fan of those films) and the amount of unnecessary creatures (I think the porgs were the least of this movie's problems - don't get me started on the sea cow thing) were just ridiculous. The whole casino scene... ugh! Not the mention the humour...
What the heck was the film trying to do? From the first two minutes when Poe was playing the "I'm on hold" prank I was really hoping that wasn't setting the tone for the film and oh my... it did   The original three Star Wars films had silly humour in them - but that was part of the charm, and not rampant throughout. I felt this new film just way overdid it - it was too frequent; too smart ass.... I feel it was veering wildly away from true star wars, and coming off like any other action filled, rely on the special effects, jump the shark modern sci fi with non-stop chuckles to keep the audience entertained. And perhaps that's what is was - just entertainment. How else to explain the ninja weapon weilding red guards after snork or snope or whatever he was called got nailed? And Fasma... really? What a stupid character. About as bad as Hux.
Come on... this is Star Wars. I'm not a die hard fan, but I cherish the first three films and I think there is a certain level in its universe that sets it apart, which still translates really well with a modern audience despite its age. Was this new film trying to appeal to a more modern audience with different expectations? The Force Awakens was a bit silly in places, but I had lots of fun watching it on first viewing and it managed to maintain the Star Wars spirit. In this one, many of the characters for me felt largely petulant and childish. Even BB8 annoyed me. Kylo was a slight improvement in this film - I liked the internal conflict we saw in this segment of the series and it will be interesting to see where it leads, but at the moment I'm just anticipating perhaps a last minute redemption a bit like Vadar in Return of the Jedi.
Oh boy.... what a rant. So, I'm clearly in the critical camp, perhaps a bit too old school?

I'm sure there are those here who loved it - please tell us why, and feel free to theorise about where the finale is headed

And in the interests of friendly, healthy discussion, everyone keep your lightsabers down!
