It’s probably always safe to assume that fans/audiences underestimate how much thought filmmakers put into their choices. Most don’t realize how long and intensive the process is. In the case of TFA, JJ was essentially writing that movie from the beginning of 2013 all the way through to the end of 2015 (plus being a fan he probably came in with a lot of prior thoughts about the nature of things in the universe).

This is not me saying you can’t complain about the choices that were made, but it’s unfair and innacurate to suggest that the choices were made thoughtlessly.

For me, if it’s a choice you don’t like, I think it’s interesting to consider why they might have made such a choice - typically it’s in service of something else that they believe is more important than the thing you dislike about it.
