What would you say the flaws were? Sounds interesting considering you say these are things that affect all major movies.
In this age of TV series, even movies are created in the same vein. Thus there are fewer and fewer movies that feel complete from start to finish. They are ended and left open so that audiences are compelled to come back just to see the next episodes, and not perhaps because the movie was actually that good. Of course Star Wars was created like this from the start, but it still seemed too much like Part I instead of a stand alone movie in a trilogy (also as far as I know Lucas made Star Wars as a cash cow anyway).
Second, movies are very formulaic. They all follow a very similar path, never steering too far from the safe zone. Similarly, there is very little innovation. It is very apparent in the plethora of remakes, reboots, prequels, sequels, etc. we're seeing. It is no surprise TFA is almost an exact copy of A New Hope. People have defended this decision, saying that it is supposed to reintroduce the universe, get us into the "vibe" again and to set up the sequels (first point). To me it simply feels like a convenient excuse to get another free pass and a successful movie. For some reason the prequel trilogy didn't feel the need to have a recap as Episode 1.
Too much action. Instead of exploring the time gap between TFA and Episode 7; shedding some more light on the main characters, or spending time properly developing them, we get one explosion after another. We're seeing solar systems casually being blown up, suns getting drained dry, Deathstar vol. 2 getting destroyed after 10 minutes, the Resistance celebrating victory, the birth of a new jedi, etc. all in one go without any buildup, backstory or suspense. The intense political struggle over the entire galaxy between the Empire/First Order and the Republic is completely lost.
The same can be said about the characters. They are bland and underdeveloped. One of the most interesting things this movie could have done is going in depth with Finn. But instead of actually exploring his path to overcoming the life he was raised into from pretty much birth, we're only given the tip of the iceberg with him suddenly discovering morals out of the blue. Not only that, he is relegated to being a comic relief throughout the movie, only waiting to be saved by Rey. I know they were playing with the gender stereotypes, and it would have been ok if she wasn't written as a Mary Sue. Rey is the worst character in the movie without question. From a desert planet scavenger into a force user, an expert mechanic, an ace pilot and a considerable lightsaber combatant in 1 day. She learns that the force is not a myth and a few hours later can already do jedi mind tricks and block out a Sith apprentice. The general defense to her is "stay tuned for the next episodes of Star Wars to find out why Rey is so badass". I already talked about that. I did like Kylo Ren, I think he was well written.
Also, a more general problem. When Fallout 4 came out, there was a drama about one gaming site giving the game a measly 7 out of 10, when every other review site didn't go below 8. The actual quality of the game aside, there is an apparent problem in the rating system as a whole - scores are extremely bloated. 7 was seen as a piece of s***, while numbers themselves show 7 is way above average and should be considered good. When looking at the scores given to TFA for example, in the last days of December, about 35% of the ratings it got were 10. It currently stands at 8.5 (and slowly dropping). I don't know who in their right mind would rate this movie a perfect 10. When I gave it a "solid 5, maybe 6 out of 10", I'm saying the movie wasn't bad, just slightly above average.
