This is super corny (and I can't tell if it's in a good way or not). It's hard to pinpoint at first what's worse- the acting or the writing, but I think I'm going to say the writing edges out the acting just a hair on the cringe-level. The overarching story is fantastic, the premise is that the protagonist (Lindy) who happens to be some hacker genius, has an online stalker (who shows up after her friends signed her up for an online dating service) who is an even better hacker than her. The stalker is a serial killer and pretty much kills a new person every episode. It's so good because it caught me by surprise when they revealed who it was, so kudos to the writers for that. However, the dialogue is extremely cringe inducing and doesn't give the weak actors a lot to work with. I will say that Victoria Justice is excellent in this, her acting pretty much holds the entire show together.
I do love the chemistry between Lindy and Tommy, it really doesn't get better than that for any TV show. I also love that it's a short series, so there's not a lot of filler content to drag out the story line. Despite some plot holes, questions do get answered every week (when will writers learn that this is what viewers want?). Here's what's annoying: this show got cancelled so there is no season 2- which means even though you find out who the serial killer is, there are still unanswered questions and unresolved issues by the end of it. Despite how cheesy this show is, it is great for guilty pleasure watching and I genuinely hope it gets picked up for season 2 by another network.
