Everything with a (personal) Plot twist or mind f**k in the middle or at the end I watched!
(Complete personal view) This contains content that surprised me towards the end of the film/series (whatever) with the (for me) unpredictable twist. Sometimes it can also be content which just leaved me with an empty brain alone...
No guarantee for proper arrangement (everything is just a personal opinion)! This list is growing and expanding over time...
