This movie essentially pulls the same stunt that created Star Trek: Into Darkness (by the same Director):
- Pick out the best of the series (in Star Trek, the Wrath of Khan is widely celebrated as the best of that cannon) and re-do it. The Force Awakens is a tweaked copy of the original 1977 movie.
- Follow roughly the same basic plot points, but make it hip and cool. Cram in a bunch of referential jokes and a romance that doesn't really belong.
- This force goes to 11. Ray is now essentially Marvel's Jean Gray, meaning the force is now essentially a mutant psychic superpower similar to the X-Men character, where before it was a latent ability that required loads of training. Also, you get to mysteriously know how to fly a space ship
- Dialog. Even though I wouldn't call the original series dialog excellent, this script was particularly hammy and well out of step with the color of its original characters.
- Loads of plot errors. Skywalker's location doesn't correspond to any known star charts ... oh wait, there it is. Then there's a weapon that shoots across massive distances without entering hyperspace. Later, R2-D2 wakes up a the convenient time to move this BS forward.
- Photography. Changes dramatically over the course of the film. It starts out looking very similar to the original Star Wars and then turns into a dyslexic and tedious laser festival. Pew pew pew.
