Finally checked out the final two episodes of Season 2. This season got away from me. I was hooked into Season 1, but struggled this season, and I skipped a good deal of it. I am glad I saw the finale though because it reminded me of just how good this show can be. The cast, character work, and the musical choices were all good. My biggest quibble is that I wish the Masters of Disaster had costumes. Also, I'm not a fan of where they appear to be going with Grace (I wish she was an Amazon).
But overall, I thought it was a good debut for Jennifer as Thunder (and I like her suit the best on the show), and I also liked what the tease for Season 3 appears to be about. Here's hoping Baron Bedlam will be showing up at some point. (Also, when Jennifer mentioned 'static' in terms of how her powers might affect her hair, I couldn't help but hope that the Static will be showing up at some point. I thought he would be a good love interest for her, but with the reemergence of Khalil, I don't see that happening).
I'm glad they've put Tobias on ice, without killing him. He was pretty good-as he usually is-in the finale, and I wouldn't want them to kill him off, at least not yet. However, I would like to see the family take on other villains as well, and bring Tobias back at some point down the road.
