Emesis Blue has one of the best concepts I have seen in a horror movie ever. Taking the most integral part of any multiplayer shooter, and turning it into the stuff of nightmares. This alone makes Emesis Blue a fantastically eerie time.
This movie definitely goes for a more eerie and strange approach, rather than a downright in your face scary way. Personally I really like this direction and really makes it stand out as a movie tonally. However I think the eerie feeling it was going for is a double edged sword, because at some points in the film it gets a little drawn out and boring while the mercs are walking around and exploring the building. For the most part however it worked wonderfully.
It does a very good job at giving this feeling of something isn't quite right with the lovable TF2 characters we all know and love. The animation itself is outstanding, and the visual shots in the movie are very impressive. Especially for Source Film Maker.
The story however, is extremely hard to follow. Emesis Blue really keeps its cards close, and doesn't tell you the story upfront. You kind of have to pay close attention to the film to get all the pieces to complete the puzzle, which can be seen as a negative or a positive.
What I'm saying is that I shouldn't have to watch a video to explain the story for me.
The voice acting reigns from decent to great, some of the actors do a great job of impersonating the TF2 mercs. While some do an alright, but serviceable job.
All in all, Emesis Blue is a great animated horror movie. Horror fans shouldn't sleep on this one just because it's animated or because it uses TF2 characters. Emesis Blue provides some of the greatest horror moments in a very long time.
