What an unoriginal Star Wars film- copied so many aspects of original films

Rating: 4/10 (25 December 2015)

Don't get me wrong, the cinematic a and 3D effects were top notch but for anyone who grew up with the original franchise this film was a mix of story lines of New Hope and Empire Strikes Back. I think this is targeted at those who grew up with the 1997-2005 trilogy and made for today's teens. Firstly, I'm not bragging or saying my claims are more valid than anyone else's opinion but I minored in Film and Media Studies in college with a 3.65 GPA in my minor. Let's go over the numerous shortfalls and storyline redundancies in the franchise. First, it's 30 years or so later in the Star Wars world yet the only effective way to send messages still is via hand carried messages stored on robots- first R2D2 and now the new little robot ( kinda dumb). Second, how has the new Empire have the capability to build a machine to harness the sun's power but no way to stop intruders from getting in to blow it up? You'd think they'd have multiple redundancies built in to protect a massive failure. If it's that important, have multiple guards near every door and heavy guns on top in order to stop a full on assault. Next, I doubt it's a straight shot to the targeted planet that's light years away- there will be other stars or planets blocking a straight line shot. Second, it should take years for the blast to arrive- not seconds, otherwise if you flew light speed from the first planet, you smash into the next in less than a second. Next, unlike the shock of hearing Darth Vader was Luke's father, I could see 30 minutes ahead of time that Han and Lea were the parents of the new sith. Having Rey travel to train under Luke is exactly like Luke traveling to find snd train under Yoda. Luke and Rey will now train ( possibly find scattered Jedi across Galaxy) to fight the giant Sith and the other New Order team. I give the effects 9.4/10 and the story 4/10. Wow, I could've come up with a better story arc for this film and have had Abrams fill in the details. Anyone else who grew up on the original trilogy feel betrayed by this film and it's supposed turning points? How did this get such good reviews?
This film will make a billion in U.S. And a billion over seas- hell, the last Transformers, which was one of the worst, most plot holed film I've seen with a major release made a ton of cash in China. I expect this 7/10 movie to do the same.
For those whom liked it, what did you like beyond the 3 D and effects? What did you find original about the story?
