Not an overly big fan of the secretary and the Megawatt character. I also miss more fighting/action scenes. There's too much talking, so it starts to resemble a soap opera.
The ending is a bit underwhelming, too. I wanted to see the threat of a new supervillain/a new threat on the horizon so bad.
Then again, I haven't read the comics. Maybe the nerds can shed more lights on this.
All in all, for someone who has grown up with TV series seasons lasting 20+ episodes, today's "seasons" are a bit of a joke.
