Massive disappointment on first viewing, but since then I have seen it 3 times.
On first viewing, in 3D it seemed like the movie starts off from out of nowhere. Yes, the so did the original but I expected more here. I immediately starting thinking how good the original were and knew this would never match it. However, I instantly found the two male leads likable. Same with Rey at first...until she opened her mouth.
The second the spoke with BB-8, I watched the remaining 30 mins or so with my arms crossed. Terrible actress. Then I saw her fly the falcon WITH NO TRAINING whatever. I had to take a break here.
Went to get a drink, came back and Han Solo and Chewie were on screen. I smiled, took my seat, and to be honest, rather enjoyed the rest of the movie... up until the final battle with Ren. That was bad, I get he was wounded, but by far the weakest of the villains seen a Star Wars movie. Overall I was not pleased.
2nd viewing, (no 3D, ie the best way to view a movie) I had similar complaints, plus how not only she mastered flight and saber, but also mind control, something Luke didn't do until ROTJ. However, as this was not in 3D, I got to appreciate some of the choreography and direction a lot more. There were some very good scenes shot here. The highlight being when Han and Chewie show up and the battles that take place on Takodana and Starkiller.
3rd viewing was in 70mm imax. Nice novelty, and while the movie is fun to watch, overall, there is just too much wrong with it and not enough original ideas.
Final thoughts are Poe, Finn and BB8 are great. Rey is just feminist propaganda. I don't like her face. Ren is a pussy. I don't like his face either. Phasma was a pushover. Final fight was terrible. Disappointing ending. I do however like Rey's theme. A nice addition by Williams.
3/5 and that is being VERY generous.
