Not bad for a premiere episode. SFX are decent for a TV budget. I hope we quickly start getting away from 'Oh, I hope I can do this, I hope I'm good enough.' Banging that drum as a way to show she's learning and that her confidence needs building will get old fast.
What I noticed, and then kept noticing were the clumsy references to Kal. Didn't say 'Kal;' didn't say 'Superman.' It was always 'my cousin,' 'he,' 'him,' 'the big guy,' etc. Maybe it was just me, but every reference to 'him' plopped like a lead balloon. You'd think that the showrunners could've at least gotten permission to say the names. Guess not, tho, and the workarounds got rather annoying by the fifth or sixth use.
