Wow... any sort of nitpicks one might have on this are immediately silenced by the absolutely perfect mood and feel this film captured. Chell's actress captured her slightly unhinged, obbessive post-Aperture personality perfectly without saying a word, and the little touches they added built up into a fantastic piece of film. Well done, guys, well done. I genuinely love this.
For those concerned with where this falls into Portal canon, the way I read the interview in the article made me believe that they started work on this before Portal 2 came out, so there's no way they could have known what happened in it. Therefore, some inconsistencies are expected. If you're that bothered by such things, imagine this as a "what if" story- what if Chell had gotten up and was able to run away before the Party Escort Bot dragged her back in?
