Having watched every episode with netflix I havent really sensed how slow season 2 was. I'd watch like 4 or 5 in a row so when a show ended I would just move on to the next one opposed to waiting another week.
One thing I like about the introduction of all these new characters is that it follows the storyline. They said that there were thousands of people who "evolved" w/ special abilities. It would kinda suck if the story just centered around the core group and we never saw the others.
Since the show is a big endorser of violence

When characters get introduced, its sort of fun to see which ones will get their head punched in.
And since there are always new characters, the core group isnt so safe to remain on the show.
I just hope that when someone dies they dont always bring them back to life. They've done it a few times which was cool because it was understandable and it made sense. Any more and it will start to annoy me.
