Random thoughts:
This is the most I'd seen Hoechlin's Superman and I really dig him, outside of the whole "you're better than me" speech to Kara, which felt very pandering. I also enjoyed Lois quite a bit and would be totally down to watch a show about them.
After all the hype Batwoman was underused and I'm still not sure how much I'd care about a show around her. Also, it's so ridiculous that they can't use Batman.
While not as hyped, I was still disappointed with how little they used 90's Flash.
The dude that played The Monitor was great. I'm looking forward to seeing him pop up now and then.
Overall though I enjoyed this quite a bit. Yeah, there was some dumb stuff in the stories but these shows are just mindless to me anyway, and I'm fine with that. However I can't help but feel Crisis is going to disappoint. That's a big story to go for with the budget these shows have so the scope will be pared down quite heavily. I also wouldn't be surprised if this is possibly the end of at least some of the shows.
