It also seems to have a larger story building so it looks like it will be worth watching past the first season, unlike some shows that fall off because they've gotten past their major gimmick or storyline.
The only mild criticism I have is sometimes the main characters don't use their powers when they should just to advance the plot. Not just using their super speed to catch a person running at normal human speed when they could for example. This is only occasional though so it was easy enough to ignore it as a slight writing mistake.
