1) The Imposter on US Netflix. This story is so weird and cool, but it is basically about a twenty something man who impersonates a missing child and the family take him in and everything. Everyone I have showed this to has sat next to me the whole time going "wha -- what? hang on, how-?" and I have to keep a smug look on my face which obviously pains me. There is no reason not to watch this if you haven't, also I think it has won some sort of big prize (I want to say an oscar).
5) Madness in the Fast Lane which is on youtube is completely mad. The first thirty seconds are nuts, and then although it seems to calm down, you quickly realise it is actually getting more and more nuts. Also it's only an hour long so you can fit it in during anytime you have a free hour.
6) The Disappeared Investigation Discovery series, loads of which are on youtube, is something I spent almost as much time as getting my degree on during my university years. It's incredibly hammy and over-dramatic and the suspense is really laid on with a trowel, however, it is incredibly watchable. I would particularly recommend the one about Maura Murray and the one about the McStay Family, because the stories are just so unfathomably weird. (Fun fact - or maybe just a fact - once Lil, Tiff and I got home really drunk and watched one of these and all slept in a bed together, and woke up like "I had this weird dream about a family who got kidnapped..." "No way! So did I!").
Go forth and indulge your darkest desires to find out about horrible crimes and mysterious things and really good twisty plots. And, if you have any recommendations along the same vein, hit me up, because I am all in.
