What about Jews or Scientologists?
The worst part of this ridiculous movie was the whole "Christian" blood crap.
I mean saying Muslims don't count as believing in God was dumb and what about all the other religions? Like if you were Jewish? Would trolls be able to smell Jew blood? Or Hindu blood? I suppose there weren't many Jews in Scandinavia.
Otherwise it was just good escapism fun although there's alot better special effects elsewhere.
