I am going to see this movie solely because of Taika Waititi. That man is one of the better comedic directors in my mind, and was pumped to hear he was in charge a while back. I plan on seeing it later on this week and am happy to hear the good reviews on here as well as from the critics!
Side Note - Taika was a part of the New Zealand comedy troupe "So You're a Man", which included Jermaine Clemente (who I can guarantee everyone knows something he's done whether they know it or not) and Bret McKenzie (Flight of the ConChords) and if you enjoy the comedy in this movie or know/like other New Zealand comedies, I highly suggest watching the move What We Do in the Shadows, it was also directed by Taika Waititi and it is a mockumentary about 3 vampires living together from different generations and how they survive together in the same flat.
