Really enjoyed it, definitely a bit different and both funny / tense in equal measure. I wouldn't go so far as to say it was scary, but there were some effective set pieces. Liked the way it immediately felt like part of a wider story, like you could be dropped into the other countries' scenarios and see how their horror archetypes would play out (the Japanese scene was dead on). Also, the possibilities of each 'monster' being chosen for the task, rather than the Zombie Redneck Pain-worshipping family that got the gig.
Dialogue was great (nice little touches at the beginning like the piss-take of the PSA - "Where do you get these books, where did you learn to read?" "From you! I learned it from watching you!", felt like how people actually banter rather than speeches). Enjoyed Bradley Whitford and Richard Jenkins' back and forth too (the party and speakerphone scenes
)
Went batshit in the final 3rd (the unicorn was a highlight
) and began to borrow heavily from Whedon's previous stuff ('Ancient ones' deep in the ground feels oddly familiar
) but still great fun.
Also good for playing 'spot the Whedonverse actor', nice to see Amy Acker again
