I recieved this DVD as a gift and, not knowning anything about the film, sat down to watch it.
I was very impressed. The Invisible is directed by David Goyer who directed Blade 2 amongst other things, so he knows how to do a film. In this instance, there's no gore but there is a very enjoyable and well crafted story (something many would argue Blade 2 didn't have).
This film is not so much about special effects but more about character, and this is mainly displayed through the subtle use of the main character being 'Invisible'. He gets to see people when they think no-one is around, when they are showing their true sides. This is a very clever way of allowing us to see people's true nature, how they REALLY feel.
We've all wondered "What would people do if I wasn't here?" This film allows you to see someone have that EXACT experience. The fact that the film matches this up with a detective-style main plot amongst other things is pure class.
A great film, especially for the price! Buy and enjoy.
