This was an extremly well done movie! One of my favorites in fact. The feel of the movie itself was freaky as hell! (watched it with my friend at 2:00 in the morning!) The animation was top notch as the creatures were quite horrific. The plot was very interesting and gave you just enough information to keep you interested. Though at times it was a little confusing. The sound was ok as the silence added to the chill, but the characters themselves were given very little depth. The overall feel of this movie was great (in a scare the crap out of you sense) asit blended perfectly to the genre. It left you to decide for yourself. The ending was great!
this really is a spoiler:
All those lights on the tower were kids! Not to mention the fact they were screaming as the things plugged into them!
Its a movie that I would seriously love to watch again if I could find it and I recomend you do the same!
