Just saw this one as part of the Midnight Madness Programme at the Toronto Film Festival. Very fun, high energy film in the vein of something like Evil Dead 2 or Shaun of the Dead.
Really loved the vibrant colours and art direction combined with the quirky editing. Characters are all very likeable, solidly acted and have good character arcs.
Throw in some light but fairly blunt commentary on the political scene in Taiwan and several thousand gallons of fake blood, and we have a pretty entertaining film.
Bonus points for showing the best use for some nail clippers.
