Agree 100% with this. He has absolutely no agency in these movies, to say nothing of character. In the first one, he's constantly being pulled back and forth between the dueling ideologies of his two dads and only becomes Superman when he has to because Zod shows up. In BvS, he spends all of his time either moping or being pissed at Batman. Not exactly compelling, or relatable, characteristics.
I will admit that JL already looks better than the previous two movies, but I'll likely wait until it's On Demand before I watch it.
