Han and Leia were perfect in TFA.
I would have liked a bit more screen time for Leia.
You can only focus on so many characters per film. I don’t really mind the limited screen time, I don’t feel like I was missing anything from her in regards to this particular story.
And yeah she should have hugged Chewie first (although I was fine with her and Rey hugging because they would have a connection right away via the Force).
Yeah this was an obvious goof, but it’s nothing more than that - a goof. You aren’t meant to read anything into it (it’s not like Leia and Chewie ignore each other throughout the film). And yeah, nothing wrong with hugging Rey.
There was one shot of Han running from the Rathtars where you could really see his age and I would have like to see that cut.
I don’t see what’s wrong with showing his age.
And I would have only had Han use Chewie’s bowcaster the first time.
I thought that was a fun bit.
I think my only quibble is actually the moment where Han shoots a guy without looking (though even this is somewhat okay because Han checks to make sure he got him, which makes it seem more like classic Solo luck, rather than superhero skills).
