Most of you in the thread are thinking about this entirely wrong. You're justifying/reasoning why the duels were so bad with everything plot-wise in the movie but none of it really had to be in the movie to begin with.
Finn didn't need to be a stormtrooper, Kylo didn't need to be undertrained, Rey didn't need to have not had training. After seeing the movie 3 times I felt as though they almost didn't want to put lightsabers in it at all, much less have people fight with them.
It's almost as if every plot point and bit of lore in the movie is designed so they didn't have to have lightsaber duels, and what is the point exactly? Lightsabers are one of, if the not the, most popular parts of the Star Wars franchise, I'm sure they could have written a billion and one different things into the movie to give fans a decent duel.. how about not completely removing the Sith from existence for a start.
And on that point, if the Sith really have been completely and utterly destroyed and replaced with the Knights of Ren, I'm done with Star Wars, that would have to be the stupidest fucking decision of all time, the Sith are Star Wars just as much as Jedi are... who cares if the KoR are basically Sith, it would be like episode 8 replacing all Jedi with "Peacekeepers" or some bullshit.
Hello, there were such things as Sith purebloods, there is a Sith code, there is a Sith homeworld, it has always been the Jedi and the Sith, 2 sides of the same coin.
To be honest, the more I think about Force Awakens, the more I hate it.
