I have to say that my initial reaction to the start of relationship drama on the Flash Ep 2 was
However, I was shocked that eventually the characters (Iris and Gypsy) opened up about what was bothering them (like emotionally mature adults!) and their significant others (Barry and Cisco) accepted the revelation and did their best to make it right. This was great stuff! Emotionally mature characters acting like it. I was very impressed and the more I think about it, the more I'm in disbelief based on how the show was written last season.
The show was light and fun (when Killg%re wasn't killing people) and reminded me of the first season.
I like that the Thinker is getting scenes at the end of episodes from the start of the season, so we can know a little about what he's capable of and what his goals are. We don't know why yet, but that's ok. The villain isn't a complete blank slate and so we can get to know what makes him tick over the season. As has been stated many times, the best villains don't think they're a villain, so I'm hoping to see what they have in store for the Thinker.
Big improvement over the last two seasons!
