I don't understand the amount of super low rated reviews. Most of the low reviews I've seen pre-judged the show and gave 1 star because it wasn't what they were expecting (I also noticed that many of them were written after the reviewer had only seen the premiere episode, which imo really does not give the show a fair chance). This is a teen show for sure. For people coming just for SMG, it is not the new Buffy, but that doesn't mean it's bad. The horror is on par with a lot of other teen shows that deal with supernatural/horror element, but it's definitely at a 13PG/14A level. I think the show has a lot of room to grow, which is a good thing. My only qualm is a want more SMG, but now that we're deeper in the season I think her role is definitely starting to expand.
Minor SPOILERS for Buffy fans: SMG's role in this show very much gives me the experience of a what-if scenario where an alternative dimension Buffy joined The Initiative for good and is using the arson detective role as an undercover tactic, cause there is 100% more to her character than we currently know at the ep. 6 mark.
Overall I'm interesting to see how the show /story evolves.
