I found this film by accident. I never heard of it before, so I wasn't sure if I would care for it. But it was great! It is done in the still of a documentary investigation into the life of Vampires. It is a "R" rate comedy. Really well done. Four vampires share a flat and look out for one another. Special effects are excellent. These vampires that have been dead hundreds of year are trying to survive in the modern world. (There is a mini-series out based on this 2014 film. I haven't seen any of the min-series episodes but the film was very entertaining!). Of the four main characters, Viago was my favorite.
