- They weren’t necessary
You could apply this dumb argument to just about anything. You could even say that TFA wasn’t necessary.
It doesn’t move the overall plot forward thus it’s unessessary in my opinion. The only purpose it serves is to establish that Han really did revert back to his old ways
Well besides the reason you gave yourself, it is also a crucial plot point that allows Han to escape from the two gangs of criminals.
Nothing wrong with CGI.
Nothing is wrong with CG if I can’t tell it’s CG
Well at least it is far better than the collapsing planet CGI in the end.
