Kara and James' relationship? A bit dull and done no favours by that annoying love triangle with Lucy, but man would it be nice for her to be in a relationship with someone who actually respects her.
Its more important for the showrunners to cater to the audience who want to see the network standard (Merto-El/badbod with a heart of gold), instead of the paring of two characters who came together not because they fit a casting stereotype, but due to two people growing on each other (in part) as a natural outgrowth of their need to rise above the "place" they had to occupy. That was clear in season one.
James being pushed into the CatCo CEO/Guardian roles seemed out of character, but that's at least better than not seeing the character at all.
He has no connection to the rest of the characters. If it was not for Supergirl's jealousy of the Guardian / desire to unmask him, James would be less than a passing reference.
Kara becoming a reporter felt like an unflattering rip-off of Superman, like they couldn't even think of any other job she could do, but the show doesn't even commit to it, she just slaps down a pile of paper in front of Snapper every few episodes and that's it.
Just one of the many ways the series had to borrow from Superman's history. The series writers appear to lack the ability to write for more than one setting, so Kara was largely dumped to the DEO, but left the Catco plot thread in place, when t was clear they were not seriously exploring her life as a reporter.
The show's plot has always been a dumb mess but the characters/acting made up for it. It just doesn't feel like enough any more.
Interesting observation.
