Underwhelming. If you are expecting something what original trilogy offered you are bound to be disappointed.

Rating: 1/10 (18 December 2015)

First of all I think most things which I thought are already written here by others. So I will try to be brief. And this is coming from a real Star Wars fan. I voted "1" simply because the score right now (8.9/10 as of this moment) is ridiculously too high for this movie.
So here is what's wrong with the film. Some people comment here that is the feeling on original Star Wars movies. I could not disagree more. It has none of the magic Episodes 4-6 have. Original trilogy is about successful symbiosis of awesome sound track/music, special effects, cast, villains, dialogues and the Star Wars universe. This one fails to have that same kind of symbiosis. 1st of all, the villain was poor. I guess it was too much to expect a new Darth Vader/Emperor type of villains as the bar was set so damn high. But the main villains in this film were simply underwhelming. Lead villain was set up very poorly. Once he starts showing flaws he becomes a bit more interesting. But it still leaves lot more to be desired. Kylo Ren is an insecure teenager with anger issues. His character destroys the sleek mysterious Sith presentation of the both prequel as the original trilogy. This is really a bad thing.
I also think the tempo of the film is simply too fast. This is my number #1 complaint. Throughout the whole movie I felt like I was watching some PlayStation game. Thank god I did not go watch it in 3D as I would have been even more annoyed. Maybe this is just the style of J. J. Abrams. But I don't think it belongs to Star Wars universe. Compare how gracefully Episode IV Death Star assault is made. The slow paced dog fights LOOK, FEEL and TASTE so much better. And it looks technically better despite being a film made in 1977 (!!!). At one point when Poe Dameron was shooting down those Tie Fighters like flies, I really had a huge face palm. Not like this, please...
Next: out of nowhere Ray figures out she has Jedi powers. It would have been better to introduce Ray to the force in similar was Luke was back in Episode IV. I also thought the ending was poor. Again it missed the graceful ending which Episodes IV-VI managed to do.
Camera moves were not smooth and the music was so horrible. This must the first time in all Star Wars movies I was disappointed by the music. That says a lot... Only salvation was this new Trilogy if J. J. Abrams is replaced by someone more competent. Too bad mr. Irvin Kershner is no longer alive. Now the weirdest thing: I actually liked Abrams's new Trek movies.
My tip: go the movies with an open mind. If you are expecting something what original trilogy offered you are bound to be disappointed. I will quote another reviewer, because it sums up it perfectly: "It's like when an unknown Chinese manufacturer decided to make a fake iPhone"
