3.5 in reality. I just couldn't get behind everything between Clary and Jace. It kinda weirded me out.
I thought the story was very disjointed too. It was all over the place at times. There were things included that didn't do much to explain what was going on... The best part was the end when they're on the ship (don't worry that's as spoiler-y as I'll get)
It's just an okay series for me so far, it's nothing spectacular.
