Living in South Korea I don't get to see nearly all the English language movies I'd like to in a given year, but in any case every December I try and play a little catch-up.
As for Swiss Army Man -- the repetitive, film-long fart joke didn't kill it for me. Using Daniel Radcliffe's corpse as a jet-ski didn't kill it for me. Using his corpse as a weapon didn't bother me at all. Terrible fart jokes and magical realism are fine by me!
What killed it was a terrible ending and the realization the the main character is basically a creepy stalker.
