No spoilers...
Not sure what movie the people that gave it 5 stars watched but this is not a 5 star movie. It is just not. You don't see people all over the theater checking the time to see how much time is left during a 5 star movie.
The emotional sections that you may have seen in trailers definitely do not have the emotional impact that you would expect.
Several parts are extremely forced and I don't mean that in a good Star Wars force kind of way.
The battles are underwhelming and the musical score does all it can to hold the movie together.
As a life long Star Wars fan seeing some old characters and meeting new ones is always fun but doesn't do enough in this one.
You can go on and on about Star Wars and whatever else you want but it still doesn't make this film any better than a lackluster attempt at saving this last trilogy.
