Also:

I never understood Finn’s motivation for fleeing the First Order and joining the Resistance, especially if he was conditioned from childhood to be evil.

It is as if a screenwriter wrote a movie about a member of Hitler Youth deciding to switch sides and fight for the Allies without explaining the motivation for his decision.

I never understood how Rey could be so talented at everything even if she is a Skywalker and even if Luke trained her as a child before Kylo Ren wiped her memory through the Force.
I never understood the relationship between the Republic and the Resistance.
I never understood how the destruction of the Hosnian system could wipe out the entire Republic star fleet.

The entire Republic star fleet is located in only one solar system in a galaxy with millions of solar systems?

I never thought that Han Solo was funny in this movie.

There are a lot of things I find objectionable in The Force Awakens
