All
LWAC efforts are worth watching but imo the earlier films are the best and the series started to get a little daft later on with Daigoro's baby cart having hidden machine guns and even travelling on skis! Still great blood splattered entertainment though!
SA automatically comes highly recommended of course and comes across as sort of a 'best-of' compilation of the initial two movies in the saga.
Good electronic score over the end credits too imo!
