This show mostly takes place in mostly in a Philadelphia townhouse and is seemingly low budget (but probably not the reality). There is very little CGI or so subtle that it appears that way. The acting is very well done - especially Ambrose, Free, Grint and Kebbell. The sound design does a lot of work on its own similar to horror movies before they were ruined by heavy-handed CGI. It's like a modern day Alfred Hitchcock production. There are very few shortcuts - everything is executed with raw talent and skill. If you're the type that likes thought-provoking mind-benders, then this show would satisfy you to say the least.
