Here's my review, or some would say critique, due to the extreme detail tha tenters these reviews I write.
Graphics: 10, because your camera footage was very clean and professional, not to mention that the lack on movement of the camera added to the air of immobility that one assumes when they talk on the phone.
Style: 9, because I found the idea of a live-action idea on NewGrounds to be very original, and in fact, refreshingly humourous.
Sound: 8, because the sounds were dedicated, and the quality was good, however, the worms' voices got a little on my nerves.
Violece: 5, due to the implied loss of a head on a HellHound, which I find to be sad. Not to mention that the worms were very aggressive, in true Worms style.
Interactivity: 0, because there was none. Anyone who votes higher than 0 for interactivity for something like this would be a major fanboy, or a complete twit, possibly both.
Humour: 10, as your story was well thought-out, and the script cleverly written. Heck, even my dad enjoyed it, he thought it was alright.
Overall, you get a 9, due to the effort and brilliance that you've put in with making this. BTW, does the movie get released here in Australia? If so, where would you release it?
